        McKEAGUE, Circuit Judge. Plaintiff-Appellant Tommy J. McClanahan appeals the district
court’s denial of his motion for summary judgment and the grant of the Defendant-Appellee
Commissioner of Social Security’s motion for summary judgment affirming the Commissioner’s
decision and dismissing the case. McClanahan claims that the district court erred when it upheld
the Commissioner’s determination of the date of onset of his disability. For the reasons that follow,
the ruling of the district court is affirmed.

No. 05-6649           McClanahan v. Comm’r of Soc. Sec.                                        Page 2


                                           I. Background
        McClanahan first applied for disability benefits and supplemental social security income in
December of 1997, claiming that he was unable to work beginning February 28, 1997, due to
degenerative disc disease. His initial application was denied, and he requested a hearing before an
Administrative Law Judge (ALJ). Following the hearing, the ALJ issued a decision on September
20, 1999, denying McClanahan’s disability claim. The ALJ’s decision became the Commissioner’s
final decision on September 28, 2000, when the Appeals Council denied McClanahan’s request for
review.
       McClanahan filed his first complaint in federal district court seeking review of the ALJ’s
decision on October 27, 2000. The parties filed cross-motions, each asking the district court to
reverse the ALJ’s decision and enter an order to remand the case for further fact-finding. The
magistrate issued a report and recommendation, recommending that the motions be granted and that
judgment be entered. On March 22, 2001, the district court entered an order accepting the
magistrate’s recommendation in its entirety. As a result of the order, the claimant underwent
neuropsychological evaluation and a supplemental hearing was conducted.
        Following the additional development of the record, McClanahan appeared represented by
counsel on February 20, 2002, before a different ALJ, who found that McClanahan was disabled as
of July 27, 2001, due to organic brain dysfunction, but not prior to that date. The ALJ’s decision
became the Commissioner’s final decision on July 7, 2004, when the Appeals Council found no
reason to assume jurisdiction.
        On August 9, 2004, McClanahan filed a second complaint in federal district court seeking
judicial review of the ALJ’s February 20, 2002, determination. The magistrate judge issued a report
recommending the entry of judgment for the Commissioner. After overruling McClanahan’s
objections to the report, the district court entered an order granting the Commissioner’s motion for
summary judgment. This timely appeal followed.
                             II. Jurisdiction and Standard of Review
        The district court exercised jurisdiction over the final decision of the Commissioner pursuant
to 42 U.S.C. § 405(g) and 42 U.S.C. § 1383(c)(3). This court has jurisdiction over the final ruling
of the district court pursuant to 28 U.S.C. § 1291, 42 U.S.C. § 405(g), and 42 U.S.C. § 1383(c)(3).
        This court must affirm the Commissioner’s conclusions unless the Commissioner failed to
apply the correct legal standard or made findings of fact that are unsupported by substantial
evidence. Branham v. Gardner, 383 F.2d 614, 626-27 (6th Cir. 1967). “The findings of the
[Commissioner] as to any fact if supported by substantial evidence shall be conclusive . . . .” 42
U.S.C. § 405(g). “Substantial evidence is more than a scintilla of evidence but less than a
preponderance and is such relevant evidence as a reasonable mind might accept as adequate to
support a conclusion.” Besaw v. Sec’y of Health and Human Servs., 966 F.2d 1028, 1030 (6th Cir.
1992). “The findings of the Commissioner are not subject to reversal merely because there exists
in the record substantial evidence to support a different conclusion. . . . This is so because there is
a ‘zone of choice’ within which the Commissioner can act, without the fear of court interference.”
Buxton v. Halter, 246 F.3d 762, 772 (6th Cir. 2001) (citations omitted). This Court reviews
questions of law de novo. Smith-Wilkins v. Sec’y of Health and Human Servs., 880 F.2d 864, 866
(6th Cir. 1989).
No. 05-6649           McClanahan v. Comm’r of Soc. Sec.                                            Page 3


                                            III. Analysis
        McClanahan brings two issues on appeal. First, he claims that the ALJ committed error
because he applied the wrong legal standard when he determined the onset date of McClanahan’s
disability. Second, he claims that the ALJ erred in finding that July 27, 2001, was the date of onset
for his disability.
       A. Disability Determination
        An ALJ engages in a five-step sequential evaluation when deciding whether a claimant is
entitled to social security disability benefits pursuant to 20 C.F.R. § 404.1520(a)(4). The evaluation
proceeds as follows: 1) the claimant’s work activity is considered. If he is performing substantial
gainful activity, he will be found to be not disabled; 2) the severity of the claimant’s alleged
impairments is considered, including the duration; 3) the severity of the alleged impairment is
considered compared to the disability listings, and if the impairment meets one of the listings, the
claimant is found to be disabled; 4) if the claimant’s impairment does not prevent him from doing
past relevant work, a finding of not disabled will be made; 5) finally, even if the impairment does
prevent him from doing past relevant work, the claimant’s age, education, and work experience are
considered along with the residual functional capacity to determine whether the claimant could
adjust to other work. Id.
        During the sequential evaluation, if the claimant is found to be conclusively disabled or not
disabled, the disability determination is made, and the inquiry is ended. Id. (“If we can find that you
are disabled or not disabled at a step, we do not go on to the next step.”).
       B. Wrong Legal Standard
        McClanahan first claims that the ALJ erred when he did not mention Social Security Ruling
83-20 to establish the onset date of disability, and when he did not employ the correct legal standard
in his disability determination.
       Social Security Ruling 83-20 governs the determination of disability onset date. Once a
finding of disability is made, the ALJ must determine the onset date of the disability. See Key v.
Callahan, 109 F.3d 270, 274 (6th Cir. 1997). The ruling states, in relevant part:
       Factors relevant to the determination of disability onset include the individual’s
       allegation, the work history, and the medical evidence. These factors are often
       evaluated together to arrive at the onset date. However, the individual’s allegation
       or the date of work stoppage is significant in determining onset only if it is consistent
       with the severity of the condition(s) shown by the medical evidence.
SSR 83-20 at 1 (emphasis added). Further, the ruling states that “the medical evidence serves as the
primary element in the onset determination.” Id. at 2.
        McClanahan claims that the ALJ “did not mention or apply the proper legal standard in
determining the onset date of disability. Once he found claimant disabled at Step 3 of the sequential
evaluation process, he should have established the onset date using the legal standard set forth in
Social Security Ruling 83-20.” Appellant’s Br. at 14. In particular, McClanahan urges that an
earlier disability onset date should be identified, because the ruling states:
       Particularly in the case of slowly progressive impairments, it is not necessary for an
       impairment to have reached listing severity (i.e. be decided on medical grounds
       alone) before onset can be established . . . . In some cases, it may be possible, based
       on the medical evidence, to reasonably infer that the onset of a disabling impairment
No. 05-6649           McClanahan v. Comm’r of Soc. Sec.                                          Page 4


       occurred some time prior to the date of the first recorded medical examination, e.g.
       the date the claimant stopped working.
SSR 83-20 at 2.
        McClanahan argues that the ALJ’s decision requires this court to remand the case “so the
ALJ can create a record which forms a basis for the onset date” because the opinion fails to mention
SSR 83-20, fails to explain the legal standard used to establish the onset date, and fails to offer any
rationale for the onset date the ALJ identified. Appellant’s Br. at 25.
       1. ALJ not required to specifically mention SSR 83-20
       McClanahan advances no legal authority for his theory that the ALJ applied the wrong legal
standard when he failed to mention SSR 83-20 during the disability determination. He cites to
Blankenship v. Bowen, 874 F.2d 1116, 1122 n.9 (6th Cir. 1989), wherein this court stated that Social
Security Rulings are binding on all components of the Social Security Administration. These rulings
represent “precedent final opinions and orders and statements of policy and interpretations that [the
Social Security Administration] ha[s] adopted.” 20 C.F.R. § 402.35(b)(1) (internal citations
omitted). While we agree with this assertion, we do not find that it stands for the proposition that
an ALJ must refer with specificity to Social Security Rulings when making disability
determinations. Because the ALJ conducted the analysis required by the Ruling, his failure to
mention it by name is not fatal to the decision. See Pugh v. Bowen, 870 F.2d 1271, 1274 (7th Cir.
1989).
       2. The ALJ followed the dictates of SSR 83-20
        We find that the ALJ did follow the requirements of SSR 83-20 when rendering the disability
determination, even though the ruling was not specifically mentioned. Contrary to McClanahan’s
assertion, the ALJ performed a thorough and considered review of the record. He found that
McClanahan met the criteria for organic brain dysfunction based on the findings of the
neuropsychological testing performed by Dr. Miller. In his report, the ALJ summarized his rationale
for his determination. He stated:
       1. The claimant, who met the insured status requirements of Title II of the Act on
       February 28, 1997, and through the date of this decision, has not engaged in
       substantial gainful activity since such alleged disability onset date.
       2. The medical evidence establishes that the claimant has “severe” impairments as
       set forth in the body of this decision.
       3. The claimant’s organic brain dysfunction has met the criteria of section 12.02 of
       the Listing of Impairments, from July 27, 2001, and thereafter, but not prior thereto.
       4. Prior to July 27, 2001, the medical evidence fails to establish that the claimant
       had impairment(s) satisfying the criteria of any section of the Listing of Impairments.
       His borderline intellectual functioning and depression imposed no more than
       “moderate” restriction of daily activities, or ability to maintain social functioning,
       or ability to sustain concentration, persistence, or pace. There were no repeated
       episodes of mental decompensation, and no showing of inability to function
       adequately outside of a highly supportive setting.
       5. The claimant’s subjective complaints of functional limitation are disproportionate
       to the medical evidence and are not fully credible for the period prior to July 27,
No. 05-6649          McClanahan v. Comm’r of Soc. Sec.                                          Page 5


       2001, considering both medical and other evidence of record.              (20 C.F.R.
       §§ 404.1529 and 416.929).
       6. From February 28, 1997, through July 26, 2001, the claimant had the residual
       functional capacity to perform light exertion, provided he perform no more than
       simple, unskilled tasks and perform no work requiring close interaction with co-
       workers or supervisors.
       7. From February 28, 1997, through July 26, 2001, the claimant was unable to
       perform past relevant work.
       8. From February 28, 1997, through July 26, 2001, the claimant was a “younger
       person”.
       9. The claimant has marginal literacy.
       10. Based on an exertional capacity for light exertion and the claimant’s age,
       education, and work history, 20 C.F.R. §§ 404.1569 and 416.969 and Medical-
       Vocational Guideline Rule 202.18 would direct a finding of “not disabled.”
       11. Although additional nonexertional limitations did not allow the claimant to
       perform the full range of light exertion, using the cited rule as a framework for
       decision making, there were significant numbers of jobs in the regional and national
       economies that he could perform prior to July 27, 2001, examples of which are set
       forth in the body of this decision.
       12. The claimant was under a “disability” as defined in the Social Security Act and
       Regulations commencing July 27, 2001, but not prior thereto. (20 C.F.R.
       §§ 404.1520(d), (f) and 416.920(d), (f).)
Tr. 277-78.
       In the body of his report, the ALJ discussed the method he used to ascertain the disability
onset date. He stated:
       Although organic brain dysfunction has been diagnosed, the undersigned notes that
       medical documentation thereof did not occur prior to Dr. Miller’s report of July 27,
       2001. Consequently, the medical evidence cannot support a finding that such
       impairment met the criteria of Listing 12.02 prior to such date. Therefore, it remains
       for consideration whether Mr. McClanahan was disabled prior to July 27, 2001.
Tr. 273 (emphasis added). The ALJ then engaged in a careful review to ascertain whether
McClanahan’s medical record supported a finding of disability onset prior to July 27, 2001:
       Consultative examiner Robert Spangler, Ed.D., noted in January 2001 that Mr.
       McClanahan was oriented in all four spheres, that he had adequate recall of recent
       and remote events, and that he repeated 3 words after 5 minutes, connoting
       significant short-term memory capacity. He also performed serial five subtractions
       without error and showed no loose associations or illogical language. He endorsed
       preparing his own meals when his wife was at work, watching television with some
       difficulty in concentration, taking out the trash, and playing with his dog. He
       endorsed physical difficulties and pain as contributing to his limited activities. The
       examiner assessed him as having adequate social skills, as well. He had received no
       specialized mental health treatment prior to January 2001. Consistent with Dr.
No. 05-6649           McClanahan v. Comm’r of Soc. Sec.                                         Page 6


       Spangler’s findings and assessments, and the opinion of a designated State Agency
       medical consultant in January 2001, the undersigned concludes that the “B” and “C”
       criteria of section 12.04 of the Listing of Impairments were not met, in that no more
       than “moderate” restriction of activities of daily living or ability to perform social
       functioning or to sustain concentration, persistence, or pace were present. Similarly
       there is no evidentiary basis for concluding that he was incapable of functioning
       adequately outside of a highly supportive setting. Thus, the undersigned finds that
       no mental disorder met listing criteria prior to July 27, 2001.
Tr. 274. The ALJ reviewed the record for indications that disability onset occurred prior to the July
27, 2001, diagnosis date, and found that the medical evidence did not support such a finding. While
he did not specifically mention SSR 83-20, he followed the guidelines set out in the ruling.
        McClanahan claims that pursuant to SSR 83-20, the ALJ should have called on a medical
expert to infer the date of onset in his case, because “the claimant presented a prima facie case of
disability and the burden shifted to the Commissioner.” Appellant’s Br. at 24, n.9. In support of
this theory, McClanahan relies on the following excerpt from SSR 83-20:
       In some cases, it may be possible, based on the medical evidence[,] to reasonably
       infer that the onset of a disabling impairment occurred some time prior to the date
       of the first recorded examination, e.g. the date the claimant stopped working. How
       long the disease may be determined to have existed at a disabling level of severity
       depends on an informed judgment of the facts in a particular case. This judgment,
       however, must have a legitimate medical basis. At the hearing, the administrative
       law judge (ALJ) should call on the services of a medical advisor when onset must be
       inferred.
Id. (emphasis added). McClanahan then attempts to buttress his burden-shifting argument by citing
Howard v. Commissioner of Social Security, 276 F.3d 235, 238 (6th Cir. 2002). In Howard, this
court stated: “The Commissioner has the burden of proof only on ‘the fifth step, proving that there
is work available in the economy that the claimant can perform.’” Id. (quoting Her v. Comm’r of
Soc. Sec., 203 F.3d 388, 391 (6th Cir. 1999)). The case offers no opinion concerning the burden of
proof for the determination of onset date, nor does it even imply that the burden would shift to the
Commissioner. In fact, it states conclusively that the burden only shifts at the fifth step of the
disability determination inquiry.
       Upon review, we find no merit to McClanahan’s claim that the ALJ erred by not requiring
a medical expert to infer an onset date pursuant to SSR 83-20. The portion of the ruling that Mc-
Clanahan relies on contemplates situations when an individual claims disability and there is no
development of the medical record on which the ALJ can rely to ascertain onset. This is not the case
here. In fact, McClanahan’s medical record was well developed and carefully reviewed by the ALJ.
       Further, the ALJ did elicit testimony relevant to the disability onset date from Dr. Buckner,
a psychologist. Buckner opined that McClanahan’s organic brain dysfunction may have been caused
by head injuries that he sustained in 1996 and 1997, but he could not say so with certainty. During
questioning, Buckner stated:
       Buckner: You know, the second one, the second [head] injury could be the cause of
       most of the problem. I’m not sure which one was the cause, but either one, you
       know, could have caused that [organic brain dysfunction]. And the second one could
       be the reason that he seemed to get so much worse.
       ALJ: But we really don’t know, do we?
No. 05-6649           McClanahan v. Comm’r of Soc. Sec.                                          Page 7


       Buckner: No. It’s pretty difficult with – you know, with closed head injuries to
       know for sure.
Tr. 624. During oral argument on appeal, counsel for McClanahan was questioned concerning
whether he attempted to elicit testimony from Buckner concerning the date of disability onset. He
replied that he had not, because he believed the burden was on the ALJ to establish the onset date,
and further, he believed that he had “won” once Buckner had opined that the second head injury
could have been the cause of most of the problem.
        We disagree with McClanahan’s assertion that the ALJ failed to follow the correct legal
standard in this instance. His assertion that the ALJ had the burden of proof to establish the onset
date is unsupported by any legal authority, and runs counter to the general regulatory burden of
proof that requires claimants to prove their disability to the Commissioner. See 20 C.F.R.
§ 404.1512 (a). Further, counsel may not now complain because he failed to cross examine Buckner
when he had an opportunity to do so, just because he believed that Buckner had offered a favorable
opinion. See, e.g., Baranich v. Barnhart, 128 F. App’x 481, 490 (6th Cir. 2005) (finding that ALJ
committed no error when attorney voluntarily abandoned questioning of vocational expert).
         McClanahan next argues that the ALJ erred in proceeding to step four of the inquiry after
he determined that McClanahan was disabled after July 27, 2001, at step three of the analysis. He
claims that pursuant to 20 C.F.R. § 404.1520 (a) (4), “the ALJ should not go on to the next step. The
ALJ should have applied Social Security Ruling 83-20.” Appellant’s Br. at 16. This argument is
unavailing for two reasons. First, McClanahan failed to raise this issue below. This court cannot
entertain an objection to a magistrate judge’s report and recommendation that was not previously
raised. “[O]nly those specific objections to the magistrate’s report made to the district court will be
preserved for appellate review; making some objections but failing to raise others will not preserve
all the objections a party may have.” Smith v. Detroit Fed’n of Teachers Local 231, 829 F.2d 1370,
1373 (6th Cir. 1987). Here, McClanahan failed to raise this objection to the magistrate’s report and
recommendation, which found no error with the ALJ’s analysis.
         Second, the sequential analysis that McClanahan asserts was improper was not improper.
The ALJ was ascertaining the status of McClanahan’s disability claim prior to the July 27, 2001,
finding of disability when he looked at step four. He engaged in this analysis in order to determine
whether McClanahan could have performed work during the period of time between his alleged
disability in 1997 and the finding of the listed disability of July 27, 2001. See Tr. 273-73. He was
not attempting to determine McClanahan’s residual functional capacity after the date of disability.
       Having found that the ALJ did not apply the wrong legal standard, we turn to the question
of whether there was substantial evidence in the record to support the July 27, 2001, onset date.
       C. July 27, 2001, Onset Date
        McClanahan next argues that the ALJ was not justified in using July 27, 2001, as the onset
date for his disability. He relies on Blankenship, 874 F.2d at 1122, to support his assertion that it
was improper for the ALJ to rely on the date of Dr. Miller’s neuropsychological examination to
determine the date of disability. In Blankenship, this court stated:
       By choosing this date [of an examination], the ALJ was, in effect, erroneously
       requiring the impairments to reach Listing severity before finding appellant disabled,
       and erroneously failing to draw any inferences from the medical and other evidence
       as to whether appellant was able to engage in substantial gainful activity prior to the
       expiration of his insured status.

Id. McClanahan asserts that Blankenship “observed that common sense and Social Security Ruling
83-20 dispel the notion that a claimant suddenly becomes disabled on the date of the examination.”
Appellant’s Br. at 21 (citing Blankenship, 874 F.2d at 1122).
        McClanahan then identifies entries in the record to support his claim that he was suffering
from a disability much earlier than the July 27, 2001, examination date. He claims that the ALJ
failed to consider the aforementioned testimony of Dr. Buckner, who opined that McClanahan’s
organic brain dysfunction may have been caused by earlier head injuries. McClanahan also points
to Buckner’s testimony concerning his depression as evidence of earlier disability. At the hearing,
the ALJ questioned Buckner about McClanahan’s history of depression:
       ALJ: We didn’t talk about 1204 [depression] with the psychologist. Let me ask a
       couple questions. Have there been any episodes of decompensation with this
       individual on the basis of depression?
       Buckner: They’re – yes, appear to have.
       ALJ: Of how long a duration? If I can rephrase it, maybe it’d help. Is there a
       particular episode of decompensation you can identify from the testimony or the
       records?
       Buckner: Dr. Nevils in his – in describing the background, says that Mr.
       McClanahan reports in that January ‘99 evaluation of having been depressed for the
       last one and a half years. He’s also showing some paranoia at that point . . . .
       There’s a suicide attempt reported in 1999. I would consider that, you know,
       decompensation, deterioration.
       ALJ: None of them required psychiatric hospitalization, though, did they?
       Buckner: I didn’t see any record of that.
Tr. 633.
         In response to McClanahan’s claim that the ALJ failed to consider important evidence, the
Commissioner argues that the ALJ’s finding is supported by substantial evidence in the record,
notwithstanding the aforementioned testimony. The Commissioner points out that although the
medical record includes the reports of the two head injuries suffered by McClanahan, the record
does not show that he was suffering from organic brain dysfunction prior to July 27, 2001. Dr.
Huskey, McClanahan’s treating physician, made no entries in the medical record following the 1997
head injury through 2001 suggestive of organic brain dysfunction. His basis for the claimant’s
disability claim was degenerative disc disease.
        Further, Dr. Spangler, a consultative psychologist for the State of Tennessee, reported that
in January of 2001, “Mr. McClanahan had adequate recall of remote and current events; repeated
three words after five minutes; repeated seven numbers presented serially; knew the current
president and two recent predecessors and easily performed serial fives.” Appellee’s Br. at 33
(citing Tr. 392). The Bender Visual-Motor Gestalt test administered in January of 2001 indicated
no organic brain dysfunction. Id. In March of 2001, Dr. Huskey reported that he had never
diagnosed McClanahan with mental retardation, and that he had never referred him for any mental
health treatment. Id.
       In sum, during the four-year period beginning in February 1997, when Mr.
       McClanahan complained to Dr. Huskey of seeing dots [after his head injury] to and
       including his March 2001 examination with Dr. Huskey, Dr. Huskey never

       diagnosed a neuropsychological condition. Four consultative examiners reported
       multiple negative findings, and Dr. Spangler administered a neuropsychological test
       (the Bender Visual-Motor Gestalt) just six months before Dr. Miller’s examination,
       the results of which were completely normal. The ALJ could easily rely on this
       plethora of evidence to find that Mr. McClanahan’s disability did not begin until Dr.
       Miller found medical signs of, and diagnosed organic brain dysfunction on July 27,
       2001.
Appellee’s Br. at 34.
        Concerning McClanahan’s claim that he was disabled because of depressive symptoms, the
Commissioner states that the ALJ properly relied upon the findings of the state disability medical
consultant’s opinion as well as the rest of the record to find that McClanahan’s depression was not
disabling any time prior to July 27, 2001. See Barker v. Shalala, 40 F.3d 789, 794 (6th Cir. 1994)
(finding that a state agency medical consultant’s opinion supported by the opinion of a consultative
examiner may constitute substantial evidence for an ALJ’s determination). The record shows that
Huskey never referred McClanahan for any mental health treatment during the years in question.
And, although Buckner testified that McClanahan displayed symptoms of depression, his testimony
does not support the listing requirements under 20 C.F.R. pt. 404 app. 1 for disability due to an
affective disorder.
        We agree with the Commissioner. Substantial evidence exists in the record to support the
ALJ’s decision that the plaintiff was not disabled before July 27, 2001. McClanahan initially
applied for benefits complaining of back pain and degenerative disc disease. The medical records
of his primary care provider, Dr. Huskey, and consulting neurosurgeon, Dr. Killeffer, give no
indication that McClanahan was suffering from organic brain dysfunction or a disabling mental
health disorder. See Tr. 221-27, 228-34. Further, during the period of alleged disability, four
consultative psychological examiners, Drs. Nevils, Page, Spangler, and Abraham, did not find that
McClanahan met the listing level for a disabling Affective Disorder. See Tr. 202-07, 208-20, 389-
90, 396-97. Further, the findings of an ALJ are not subject to reversal merely because there is
substantial evidence in the record to support a different conclusion. See Buxton, 146 F.3d at 772.

       We also find Blankenship easily distinguishable from the facts here. In that case, we stated:
       Although the Secretary is not required to present evidence that would eliminate a
       possible onset date any time from 1979 to 1984, the Secretary still must establish by
       substantial evidence that the disability began November 13, 1985 [the examination
       date]. Considering all the evidence that detracts from this finding, including
       appellant’s subjective complaints and the proper weight they are to be given, the
       Secretary has not met this burden.
874 F.2d at 1121 (internal citation omitted). In Blankenship, the claimant was diagnosed with
multiple psychiatric disorders including chronic generalized anxiety neurosis, conversion reaction,
and schizoid personality, all well in advance of his disability determination for schizophreniform
disorder. Id. In short, the medical record in Blankenship contained a plethora of evidence
supporting an earlier onset date of disability. Such is not the case here, where the bulk of the
medical evidence in the record does not support an earlier onset date for organic brain dysfunction.
In this case, we find that substantial evidence supports the ALJ’s decision that McClanahan was not
disabled prior to July 27, 2001.

                                         IV. Conclusion
       For the aforementioned reasons, the ruling of the district court upholding the Commissioner’s
finding that McClanahan was not disabled prior to July 27, 2001, is AFFIRMED.
