The Honorable Sidney A. Fitzwater, United States District Judge for the
Northern District of Texas, sitting by designation.
1. “We review the district court’s order affirming the ALJ’s denial of social
security benefits de novo and will disturb the denial of benefits only if the decision
contains legal error or is not supported by substantial evidence.” Kitchen v. Kijakazi,
82 F.4th 732, 738 (9th Cir. 2023) (emphasis added) (quoting Lambert v. Saul, 980
F.3d 1266, 1270 (9th Cir. 2020)).
2. The district court concluded that Clark forfeited her objections to the
Administrative Law Judge’s (“ALJ’s”) evaluation of the medical opinion evidence.
In her opening brief in this court, Clark fails to challenge the district court’s forfeiture
conclusion, so she has forfeited this argument. See Carmickle v. Comm’r, Soc. Sec.
Admin., 533 F.3d 1155, 1161 n.2 (9th Cir. 2008) (issues not specifically argued in an
opening brief are forfeited). And Clark’s failure to exhaust this issue in the district
court is a basis for rejecting her arguments related to that issue. See Smartt v.
Kijakazi, 53 F.4th 489, 500 (9th Cir. 2022).
Even if we were to consider Clark’s arguments, we would find them to be
unpersuasive. Clark argues that clinical findings by her treatment providers fully
undermine Cary Jasper’s (“Jasper’s”) opinion, but “[w]e may not reweigh the
evidence or substitute our judgment for that of the ALJ.” Ahearn v. Saul, 988 F.3d
1111, 1115 (9th Cir. 2021). Moreover, Clark’s arguments concerning Dr. Melinda C.
Losee’s opinion ask us to reweigh the medical evidence and resolve inconsistencies
-2-
in Clark’s favor. But that is not the court’s role. Id. (“The ALJ is responsible for
determining credibility, resolving conflicts in medical testimony, and for resolving
ambiguities.”) (quoting Andrews v. Shalala, 53 F.3d 1035, 1039 (9th Cir. 1995)).
Similarly, with respect to her treatment providers’ observations, Clark offers no
explanation for why those observations render the ALJ’s disability finding erroneous
given the other evidence supporting Clark’s lack of severe limitations. See Morgan
v. Comm’r of Soc. Sec. Admin., 169 F.3d 595, 599 (9th Cir. 1999) (“Where the
evidence is susceptible to more than one rational interpretation, it is the ALJ’s
conclusion that must be upheld.”). And with regard to Clark’s non-examining
physicians’ opinions, Clark only alleges that the ALJ erred in evaluating Dr. Christine
Harmon’s (“Dr. Harmon’s”) opinion. But the ALJ’s finding that Clark can stand and
walk for only four hours in an eight-hour workday is consistent with Dr. Harmon’s
finding that Clark must periodically alternate between sitting and standing. Shaibi v.
Berryhill, 883 F.3d 1102, 1107 (9th Cir. 2017) (affirming denial of benefits after
finding “no obvious inconsistency” between two medical opinions and the ALJ’s
residual functional capacity (“RFC”) determination). To Clark’s benefit, the ALJ
adopted a more severe version of Clark’s limitations than did Dr. Harmon, who found
that Clark can stand and walk for six of eight hours.

3. Moreover, the ALJ did not improperly discount Clark’s subjective symptoms
testimony. Where, as here, there is no evidence of the claimant’s malingering and the
ALJ determines that objective medical evidence establishes an impairment that could
reasonably produce the symptoms of which the claimant complains, the ALJ must
offer clear and convincing reasons for rejecting the claimant’s testimony. See Smartt,
53 F.4th at 497. Here, the ALJ pointed to specific contradictions between Clark’s
testimony and the medical record. The ALJ also referenced the improvement in
Clark’s physical symptoms associated with her deep vein thrombosis. See Warre v.
Comm’r of Soc. Sec. Admin., 439 F.3d 1001, 1006 (9th Cir. 2006) (“Impairments that
can be controlled effectively with medication are not disabling for the purpose of
determining eligibility for SSI benefits.”). Similarly, the ALJ explained how Clark’s
failure to seek further migraine treatment and mental-health therapy is inconsistent
with her testimony about the severity of her symptoms.1 These justifications are clear
and convincing reasons for discounting portions of Clark’s testimony. See Smartt, 53
1
Even assuming arguendo that the ALJ’s reliance on Clark’s failure to seek
therapy was erroneous, as Clark asserts, this error is harmless because substantial
evidence supports the ALJ’s determination that Clark’s testimony about the severity
of her mental health symptoms was contradicted by the medical record. See
Carmickle, 533 F.3d at 1161 (“Contradiction with the medical record is a sufficient
basis for rejecting the claimant’s subjective testimony.”); Buck v. Berryhill, 869 F.3d
1040, 1048 (9th Cir. 2017) (“The Court may not reverse an ALJ's decision on account
of a harmless error.”).
-4-
F.4th at 496-97 (concluding that the ALJ properly discounted the claimant’s testimony
based on inconsistencies with the medical record, the claimant’s daily activities, and
the claimant’s conservative treatment). Other portions of Clark’s testimony did not
require additional restrictions in her RFC.
4. The ALJ also did not err in failing to evaluate the lay witness evidence. The
ALJ need not discuss lay witness evidence if it “is similar to other testimony that the
ALJ validly discounted or . . . is contradicted by more reliable medical evidence that
the ALJ credited.” Molina v. Astrue, 674 F.3d 1104, 1119 (9th Cir. 2012), superseded
on other grounds by regulation, 20 C.F.R. § 404.1502(a); see also Valentine v.
Comm’r of Soc. Sec. Admin., 574 F.3d 685, 694 (9th Cir. 2009) (similar). Because the
lay witness evidence was similar to Clark’s testimony, and the ALJ provided clear and
convincing reasons to discount that testimony, the ALJ did not err in declining to
discuss the lay witness evidence.
5. Finally, because the ALJ did not commit harmful error with respect to the
medical opinion evidence, Clark’s testimony, or the lay evidence, Clark has not shown
that the ALJ’s RFC assessment or hypothetical posed to the vocational expert was
based on a flawed analysis. See Stubbs-Danielson v. Astrue, 539 F.3d 1169, 1176 (9th
Cir. 2008) (affirming denial of benefits for this reason); Robbins v. Soc. Sec. Admin.,
-5-
466 F.3d 880, 886 (9th Cir. 2006) (“[I]n hypotheticals posed to a vocational expert,
the ALJ must only include those limitations supported by substantial evidence.”).
AFFIRMED.
