Appeal from the United States District Court for the Western District of Washington Michelle L. Peterson, Magistrate Judge, Presiding

Submitted September 15, 2025** Seattle, Washington

Before: W. FLETCHER and DE ALBA, Circuit Judges, and ORRICK, District Judge.***

Mark Quayle appeals the district court’s judgment affirming the

* This disposition is not appropriate for publication and is not precedent except as provided by Ninth Circuit Rule 36-3. ** The panel unanimously concludes this case is suitable for decision without oral argument. See Fed. R. App. P. 34(a)(2). *** The Honorable William Horsley Orrick, United States District Judge for the Northern District of California, sitting by designation. Commissioner of Social Security’s denial of his application for disability insurance

benefits under Title II of the Social Security Act, 42 U.S.C. §§ 401-434. We have

jurisdiction under 28 U.S.C. § 1291. We review the district court’s decision

affirming the ALJ’s denial of benefits de novo, and the ALJ’s denial of benefits

“for substantial evidence or legal error.” Farlow v. Kijakazi, 53 F.4th 485, 487

(9th Cir. 2022). We affirm.

1. We assume that Dr. Hopfenbeck’s evaluation of Quayle is part of the

administrative record that we consider in reviewing the Commissioner’s decision.

See Brewes v. Comm’r of Soc. Sec. Admin., 682 F.3d 1157, 1163 (9th Cir. 2012).

Notwithstanding Dr. Hopfenbeck’s evaluation, substantial evidence supports the

Commissioner’s determination that Quayle had the residual functional capacity

(RFC) to perform light work, see 20 C.F.R. § 404.1567(b), and detailed tasks.

According to multiple physicians who reviewed Quayle’s medical history,

Quayle’s physical impairments required him to alternate between sitting and

standing during the day, but did not prevent him from working altogether. The

physicians’ opinions were consistent with medical records demonstrating that

Quayle’s physical faculties, such as muscle strength, appeared largely intact; that

epidural steroid injections and other medications improved his symptoms, see

Berry v. Astrue, 622 F.3d 1228, 1236 (9th Cir. 2010); and that he regularly

engaged in light physical activity, such as performing chores and walking, see

2 24-4649 Thomas v. Barnhart, 278 F.3d 947, 959 (9th Cir. 2002).

Similarly, several psychologists determined that Quayle’s mental health

conditions did not prevent him from performing work that involved limited contact

with coworkers and the public. Their opinions were consistent with medical

records reflecting that Quayle exhibited no cognitive impairment in most areas,

including memory, concentration, speech, and linear thinking; and that medication

somewhat improved his depressive symptoms. The fact that Quayle continuously

worked for eight years before filing for benefits, notwithstanding that his physical

impairments and mental-health conditions dated back to 2007, further supported

the Commissioner’s determination. Ford v. Saul, 950 F.3d 1141, 1156 (9th Cir.

2020) (“An ALJ may consider any work activity, including part-time work, in

determining whether a claimant is disabled . . . .”).

That Dr. Hopfenbeck evaluated Quayle differently did not require the

Commissioner to accept Dr. Hopfenbeck’s conclusions. See Ford, 950 F.3d at

1155 (explaining that the Commissioner need not accept “the opinion of an

examining doctor [that] is contradicted by another doctor”). Dr. Hopfenbeck, the

other medical professionals, and the Commissioner relied on largely the same

records, reflecting longstanding medical conditions. At best, Dr. Hopfenbeck

offers an alternative interpretation of the evidence that might support Quayle’s

disability claim, which is insufficient to overturn the Commissioner’s decision.

3 24-4649 See Coleman v. Saul, 979 F.3d 751, 756 (9th Cir. 2020) (“[W]e will not disturb the

ALJ’s differing rational interpretation where the ALJ’s interpretation is adequately

supported.”).

2. The ALJ did not err in partially discrediting Quayle’s testimony

regarding the severity of his symptoms. An ALJ may discredit a claimant’s

testimony about the severity of his or her symptoms “by offering specific, clear

and convincing reasons for doing so.” Ferguson v. O’Malley, 95 F.4th 1194, 1199

(9th Cir. 2024) (quoting Garrison v. Colvin, 759 F.3d 995, 1014-15 (9th Cir.

2014)). Here, the ALJ explained that Quayle’s statements “concerning the

intensity, persistence, and limiting effects of [his] symptoms” were not consistent

with his “treatment record,” nor with “contemporaneous reports of actual

functioning.” See Burrell v. Colvin, 775 F.3d 1133, 1137 (9th Cir. 2014)

(“Inconsistencies between a claimant’s testimony and the claimant’s reported

activities provide a valid reason for an adverse credibility determination.”). The

ALJ then described the records and evidence supporting the ALJ’s conclusion,

including those discussed above. The ALJ also found that inconsistencies between

Quayle’s testimony and the record regarding his cannabis use undermined his

credibility. See Tonapetyan v. Halter, 242 F.3d 1144, 1148 (9th Cir. 2001) (“In

assessing the claimant’s credibility, the ALJ may use ordinary techniques of

credibility evaluation, such as considering . . . inconsistent statements in her

4 24-4649 testimony” (internal quotation marks and citation omitted)). The ALJ’s

explanation for only partially crediting Quayle’s testimony was sufficiently

specific, clear and convincing, and supported by substantial evidence.

3. Quayle is not entitled to a remand under sentence six of 42 U.S.C.

§ 405(g). Sentence six “applies only to new evidence that is not part of the

administrative record and is presented in the first instance to the district court.”

682 F.3d at 1164. Quayle concedes that Dr. Hopfenbeck’s opinion was part of the

administrative record.

AFFIRMED.
