Plaintiff, ORDER ON PLAINTIFF’S SOCIAL v. SECURITY COMPLAINT FRANK BISIGNANO, Commissioner of Social Security (Doc. 1) Defendant.

Plaintiff Karen Diosdado (“Plaintiff”) seeks judicial review of a final decision of the Commissioner of Social Security (the “Commissioner” or “Defendant”) denying her application for supplemental security income (“SSI”) under the Social Security Act (the “Act”). (Doc. 1). The matter is currently before the Court on the parties’ briefs, which were submitted, without oral argument, to the Honorable Sheila K. Oberto, United States Magistrate Judge.1 Plaintiff was born in 1974. (Administrative Record (“AR”) 82). She earned a high school diploma and completed two years of college. (AR 58). Plaintiff filed an application for SSI, alleging she became disabled on September 1, 2018, due to polysubstance abuse (methamphetamine and marijuana), hepatitis C virus, and generalized anxiety disorder. (AR 19). A. Relevant Evidence of Record2 On November 1, 2023, Dr. Tiadora Kim, Psy.D. completed a comprehensive clinical psychological evaluation, including a “medical source statement.” (AR. 986, 992). The medical source statement reflects Dr. Kim’s opinion that Plaintiff was “moderately impaired” as to her “[a]bility to maintain effective social interaction on a consistent and independent basis with others including supervisors, co-workers, and the public,” as well as in her ability to “[a] adapt to the usual stresses and pressures common to a competitive work environment including completing a normal workday or workweek responding and adapting appropriately to changes in a work setting.” (AR 992). The medical source statement also reflects Dr. Kim’s opinion that, “[p]er clinical interview and behavioral observation, [Plaintiff] has extremely poor distress tolerance and becomes easily agitated with others,” as well as the opinion that Plaintiff “likely requires some assistance and support to adapt to normative workplace stressors and be able to respond appropriately.” (Id.). B. Administrative Proceedings The Commissioner denied Plaintiff’s application for benefits initially on October 21, 2022, and again on reconsideration on November 22, 2023. (AR 100–07, 117–21). Consequently, Plaintiff requested a hearing before an Administrative Law Judge (“ALJ”). (AR 131). The ALJ conducted a hearing on May 9, 2024. (AR 51–81). Plaintiff appeared at the hearing with her attorney and testified as to her alleged disabling conditions and work history. (AR 57–77). A Vocational Expert (“VE”) also testified at the hearing. (AR 77–80). In relevant part, the VE testified that “an individual with the same age, education [as Plaintiff], and no work experience” who was “limited to medium work, simple, routine tasks, occasional interaction with supervisors, coworkers, and the public, no collaborative work on a team, no production pace work examples would be work on an assembly line or at a fast food restaurant during meal time” would be able to work as a window cleaner, waxer, and wall cleaner. (AR 77–78). The VE also testified that an inability to maintain a normal workday or workweek 20 percent of the time, being off task for 10 minutes out of every hour, and/or requiring additional supervision for 10 minutes out of every hour

2 Because the parties are familiar with the medical evidence, it is summarized here only to the extent relevant to the would be preclusive of any competitive work. (AR 78–79). C. The ALJ’s Decision In a decision dated August 9, 2024, the ALJ found that Plaintiff was not disabled. (AR 22– 29). The ALJ conducted the five-step disability analysis set forth in 20 C.F.R. § 404.1520. (AR 19– 29). The ALJ decided that Plaintiff had not engaged in substantial gainful activity since September 1, 2028. (AR 19). At step two, the ALJ found Plaintiff’s following impairments to be severe: polysubstance abuse (methamphetamine and marijuana), hepatitis C virus, and generalized anxiety disorder. (AR 19). The ALJ then determined that Plaintiff did not have an impairment or combination of impairments that met or medically equaled one of the listed impairments in 20 C.F.R. Part 404, Subpart P, Appendix 1 (“the Listings”) (step three). (AR 19–22). The ALJ assessed Plaintiff’s residual functional capacity (RFC)3 and applied the assessment at steps four and five. See 20 C.F.R. § 404.1520(a)(4) (“Before we go from step three to step four, we assess your residual functional capacity . . . . We use this residual functional capacity assessment at both step four and step five when we evaluate your claim at these steps.”). The ALJ determined that Plaintiff had the RFC: to perform medium work as defined in 20 CFR 416.967(c) except limited to simple routine tasks, occasional interaction with supervisors, coworkers and public, no collaborative work on a team, and no production paced work (work on assembly line or at a fast food restaurant during mealtime. (AR 22; see also id 22–28). Although the ALJ recognized that Plaintiff’s impairments “could reasonably be expected to cause the alleged symptoms,” the ALJ rejected Plaintiff’s subjective testimony as to “the intensity, persistence and limiting effects of these symptoms” as being “not entirely consistent with the medical evidence and other evidence in the record.” (AR 26).
