1 2 3 4 5 6 7 8 UNITED STATES DISTRICT COURT 9 FOR THE EASTERN DISTRICT OF CALIFORNIA 10 11 NICOLE MASTROMATTEO, No. 2:25-cv-00267-CKD 12 Plaintiff, 13 v. ORDER 14 COMMISSIONER OF SOCIAL SECURITY, 15 Defendant. 16

17 18 Plaintiff seeks judicial review of a final decision of the Commissioner of Social Security 19 (“Commissioner”) denying applications for Disability Income Benefits (“DIB”) and 20 Supplemental Security Income (“SSI”) under Titles II and XVI of the Social Security Act 21 (“Act”), respectively. The parties have consented to magistrate judge jurisdiction. For the 22 reasons discussed below, the court will deny plaintiff’s motion for summary judgment and grant 23 the Commissioner’s cross-motion for summary judgment. 24 BACKGROUND 25 Plaintiff, born in 1973, applied for DIB and SSI in 2022, alleging disability beginning 26 September 1, 2020. Administrative Transcript (“AT”) 17, 29. The alleged onset date was later 27 amended to February 13, 2021. AT 19. Plaintiff stated that she was unable to work due to 28 degenerative disc disease in upper back, bursitis in left shoulder, severe lower back pain, and 1 seizures. AT 79. On April 17, 2024, an Administrative Law Judge (ALJ) issued a decision 2 finding plaintiff not disabled between February 13, 2021, and the date of the decision. AT 17-30. 3 The ALJ made the following findings (citations to 20 C.F.R. omitted): 4 1. The claimant meets the insured status requirements of the Social Security Act through September 30, 2022. 5 2. The claimant has not engaged in substantial gainful activity since 6 February 13, 2021, the amended alleged onset date. 7 3. The claimant has the following severe impairments: seizure disorder, post-traumatic stress disorder (PTSD), and history of 8 alcohol use disorder with mild neurocognitive deficits. 9 4. The claimant does not have an impairment or combination of impairments that meets or medically equals the severity of one of the 10 listed impairments in 20 CFR Part 404, Subpart P, Appendix 1. 11 5. After careful consideration of the entire record, the claimant has had the residual functional capacity to perform light work except that 12 she can occasionally perform postural activities but never climb ladders, ropes, or scaffolds; she cannot work around unprotected 13 heights and must be afforded other seizure precautions; she is limited to simple tasks in a routine environment; she can occasionally 14 interact with coworkers but never interact with the public; and she is precluded from fast-paced work such as rapid assembly or conveyor 15 belt work. 16 6. The claimant is unable to perform past relevant work. 17 7. The claimant was born [in 1973] and was 46 years old, which is defined as a younger individual age 18-49, on the alleged disability 18 onset date. The claimant subsequently changed age category to closely approaching advancing age. 19 8. The claimant has at least a high-school education. 20 9. Transferability of job skills is not material to the determination of 21 disability because using the Medical-Vocational Rules as a framework supports a finding that the claimant is ‘not disabled,’ 22 whether or not the claimant has transferable job skills. 23 10. Considering the claimant’s age, education, work experience, and residual functional capacity, there are jobs that exist in significant 24 numbers in the national economy that the claimant can perform. 25 11. The claimant has not been under a disability, as defined in the Social Security Act, from February 13, 2021, through the date of this 26 decision.

27 AT 19-30.

28 //// 1 ISSUES PRESENTED 2 Plaintiff argues that the ALJ committed the following errors in finding plaintiff not 3 disabled: (1) the ALJ erred in discounting plaintiff’s subjective symptom testimony; and (2) the 4 ALJ erred in evaluating the medical opinions. 5 LEGAL STANDARDS 6 The court reviews the Commissioner’s decision to determine whether (1) it is based on 7 proper legal standards pursuant to 42 U.S.C. § 405(g), and (2) substantial evidence in the record 8 as a whole supports it. Tackett v. Apfel, 180 F.3d 1094, 1097 (9th Cir. 1999). Substantial 9 evidence is more than a mere scintilla, but less than a preponderance. Connett v. Barnhart, 340 10 F.3d 871, 873 (9th Cir. 2003) (citation omitted). It means “such relevant evidence as a reasonable 11 mind might accept as adequate to support a conclusion.” Orn v. Astrue, 495 F.3d 625, 630 (9th 12 Cir. 2007), quoting Burch v. Barnhart, 400 F.3d 676, 679 (9th Cir. 2005). “The ALJ is 13 responsible for determining credibility, resolving conflicts in medical testimony, and resolving 14 ambiguities.” Edlund v. Massanari, 253 F.3d 1152, 1156 (9th Cir. 2001) (citations omitted). 15 “The court will uphold the ALJ’s conclusion when the evidence is susceptible to more than one 16 rational interpretation.” Tommasetti v. Astrue, 533 F.3d 1035, 1038 (9th Cir. 2008). 17 The record as a whole must be considered, Howard v. Heckler, 782 F.2d 1484, 1487 (9th 18 Cir. 1986), and both the evidence that supports and the evidence that detracts from the ALJ’s 19 conclusion weighed. See Jones v. Heckler, 760 F.2d 993, 995 (9th Cir. 1985). The court may not 20 affirm the ALJ’s decision simply by isolating a specific quantum of supporting evidence. Id.; see 21 also Hammock v. Bowen, 879 F.2d 498, 501 (9th Cir. 1989). If substantial evidence supports the 22 administrative findings, or if there is conflicting evidence supporting a finding of either disability 23 or nondisability, the finding of the ALJ is conclusive, see Sprague v. Bowen, 812 F.2d 1226, 24 1229-30 (9th Cir. 1987), and may be set aside only if an improper legal standard was applied in 25 weighing the evidence. See Burkhart v. Bowen, 856 F.2d 1335, 1338 (9th Cir. 1988). 26 //// 27 //// 28 //// 1 ANALYSIS 2 A. Subjective Symptom Testimony 3 Plaintiff claims the ALJ erred in evaluating her subjective testimony and self-described 4 limitations. Plaintiff argues that the ALJ’s findings as to credibility are “very minimal” and 5 conclusory, providing so little analysis as to permit meaningful judicial review. Plaintiff further 6 argues that the ALJ’s assessment of her daily activities is flawed, as her activities are “sporadic” 7 and do not show that she can perform work on a regular and continuing basis. 8 1. Plaintiff’s Testimony 9 The ALJ summarized plaintiff’s testimony and allegations as follows: 10 The claimant alleges disability due to impairments including seizures and PTSD. She said that she experiences panic attacks and fear of 11 being in public. The panic attacks can cause seizures, which happen about two or three times a month.
