MEMORANDUM*
FRANK BISIGNANO, Commissioner of
Social Security,
Defendant - Appellee.
Appeal from the United States District Court
for the Western District of Washington
Grady J. Leupold, Magistrate Judge, Presiding
Submitted February 5, 2026**
Portland, Oregon
Before: BEA, CHRISTEN, and DESAI, Circuit Judges.
Plaintiff-Appellant Dennis J. LeDuc appeals the district court’s order
affirming the Social Security Commissioner’s denial of his application for benefits.
Because the parties are familiar with the facts, we do not recount them here. We

have jurisdiction pursuant to 28 U.S.C. § 1291. We review the district court’s
decision affirming the denial of benefits de novo, and the denial of benefits for
substantial evidence or legal error. Farlow v. Kijakazi, 53 F.4th 485, 487 (9th Cir.
2022). We affirm.
1. LeDuc challenges the Administrative Law Judge’s (ALJ) evaluation of
three medical opinions. We conclude that the ALJ’s findings are supported by
substantial evidence because he assigned more weight to those opinions that were
well-supported and consistent with the objective medical evidence. See Reddick v.
Chater, 157 F.3d 715, 725 (9th Cir. 1998).
a. The ALJ reasonably gave little weight to the post hoc written reports of
LeDuc’s primary care provider, Dr. Thomas R. Cooke, DO. “[I]f the treating
doctor’s opinion is contradicted by another doctor, the ALJ may not reject this
opinion without providing ‘specific and legitimate reasons’ supported by
substantial evidence in the record,” which “can be done by setting out a detailed
and thorough summary of the facts and conflicting clinical evidence, stating his
interpretation thereof, and making findings.” Reddick, 157 F.3d at 725 (citation
modified). The ALJ provided specific, legitimate reasons that were supported by
substantial evidence for assigning little weight to Dr. Cooke’s later written reports
because they were contradicted by his contemporaneous treatment notes and the
other medical evidence in the record.
2 24-6962
b. The ALJ reasonably gave substantial weight to the medical expert
testimony of Dr. Michael Buckwalter, MD.1 The ALJ articulated his reasons for
finding this testimony was entitled to substantial weight when considering LeDuc’s
functional limitations because Dr. Buckwalter’s opinion was well-supported and
generally consistent with the medical record. The ALJ also modified Dr.
Buckwalter’s opinion to reflect his weighing of LeDuc’s ability to engage in
postural activities, which reflects that the ALJ reasonably weighed the testimony.
c. Substantial evidence supports the ALJ’s finding that the medical expert
testimony of Dr. Steven Golub, MD was entitled to substantial weight because it
was supported and consistent with the medical record from LeDuc’s 2011
emergency room visit. The ALJ also reasonably gave Dr. Golub’s opinion less
weight than he gave to Dr. Buckwalter’s opinion because it did not relate to
LeDuc’s functional capacity during the time at issue.
2. LeDuc argues the ALJ erred by rejecting his testimony about the
severity of his symptoms. We disagree. The ALJ was allowed to discount LeDuc’s
“testimony about the severity of [his] symptoms only by offering specific, clear
and convincing reasons for doing so.” Garrison v. Colvin, 759 F.3d 995, 1014–15
1
LeDuc argues that Social Security Ruling 18-1p is relevant to this analysis.
We agree with the Commissioner that the ruling is inapplicable here because the
ALJ concluded that LeDuc was not disabled. SSR 18-1p applies to the agency’s
determination of the established onset date of a disability once a claimant is found
to be disabled.
3 24-6962
(9th Cir. 2014) (citation modified). “Contradiction with the medical record is a
sufficient basis for rejecting the claimant’s subjective testimony.” Carmickle v.
Comm’r, Soc. Sec. Admin., 533 F.3d 1155, 1161 (9th Cir. 2008).
First, as explained, the ALJ did not err in his assessment of the medical
opinions in the record. Second, the ALJ provided specific, clear, and convincing
reasons for discounting LeDuc’s testimony, which conflicted with the objective
medical evidence in the record, including his primary care provider’s
contemporaneous visit notes. This contradiction between the medical evidence and
LeDuc’s testimony was “a sufficient basis for rejecting the claimant’s subjective
testimony.” Carmickle, 533 F.3d at 1161.
3. The ALJ also permissibly discounted lay witness testimony of
LeDuc’s friend. An ALJ “must give reasons that are germane to each witness” in
order to disregard competent lay witness testimony. Molina v. Astrue, 674 F.3d
1104, 1114 (9th Cir. 2012) (citation modified); see also 20 C.F.R. 404.1527(f)(2).
Here, the ALJ satisfied that requirement. He “carefully considered” LeDuc’s
friend’s report, but because its description of LeDuc’s extreme abdominal pain
conflicted with the contemporaneous records of LeDuc’s visits with his primary
care provider, the ALJ provided a germane reason to discount the lay witness
testimony.
4. LeDuc’s arguments concerning the ALJ’s assessment of his residual
4 24-6962
functional capacity are derivative of those we have already rejected. We reject
them for the same reasons. Stubbs-Danielson v. Astrue, 539 F.3d 1169, 1175–76
(9th Cir. 2008) (rejecting claimant’s step five challenge where she “simply
restate[d] her argument that the ALJ’s RFC finding did not account for all her
limitations”).
AFFIRMED.
