R. DUNBAR,1 ) ) Plaintiff, ) ) v. ) Case No. 3:25-cv-172 ) FRANK J. BISIGNANO,2 ) Commissioner of Social Security, ) ) Defendant. )

OPINION AND ORDER This matter is before the court on petition for judicial review of a decision of the Commissioner of Social Security, filed by the plaintiff, R. Dunbar, on February 25, 2025. [DE 1]. For the following reasons, the decision of the Commissioner is AFFIRMED. Background In October 2020, Dunbar filed an application for Title XVI Supplemental Security Income, alleging a disability onset date of August 1, 2014, which was later amended to the date of the application, October 8, 2020. (Tr. 23). The claim was initially denied and then again upon reconsideration. (Tr. 142–43). A hearing was first held before an ALJ in January 2022, and the ALJ issued an unfavorable decision on March 14, 2022. (Tr. 107–32, 153–85). The Appeals Council reviewed the decision and remanded the case on August 10, 2022. (Tr. 186). Following a second hearing in January 2024, the ALJ issued another unfavorable decision. (Tr. 20). The

1 To protect privacy, the plaintiff’s full name will not be used in this Order. 2 Frank Bisignano was confirmed as Commissioner on May 6, 2025. Pursuant to Rule 25(d) of the Federal Rules of Civil Procedure, Frank Bisignano should be substituted as the defendant in this suit. No further action need be taken to continue this suit by reason of the last sentence of section 205(g) of the Social Security Act, 42 U.S.C. § 405(g). Appeals Council denied Dunbar’s request for review, making the ALJ's decision the final decision of the Commissioner. (Tr. 1). Agency regulations set forth a five-step sequential evaluation process for evaluating a claim of disability. 20 C.F.R. § 416.920(a)(4)(i)–(v); Moore v. Colvin, 743 F.3d 1118, 1121 (7th Cir. 2014).

At step one, the ALJ found that Dunbar was not engaged in substantial gainful activity. (Tr. 26). At step two, the ALJ determined that Dunbar had severe impairments of right knee chronic instability, right patella recurrent dislocation, lumbar spinal stenosis, depression, post- traumatic stress disorder, borderline personality disorder, and anxiety. (Tr. 26). The ALJ noted Dunbar’s other non-severe impairments but found that they did not impose more than a mild limitation on her work ability. (Tr. 26). At step three, the ALJ found that Dunbar’s impairments did not meet the severity of the listed impairments in 20 C.F.R. Part 404, Subpart P, Appendix 1. (Tr. 26–28). The ALJ

considered the physical impairments under various Listing 1.01 categories, including Listing 1.15 (skeletal spine disorders), and Listing 1.16 (lumbar spinal stenosis), and Listing 1.18 (major joint abnormalities). Dunbar’s diagnosis of complex regional pain syndrome was evaluated under Listing 14.09 (Inflammatory Arthritis), Listing 11.14 (Peripheral Neuropathy), Listing 1.01 (Category of Impairments, Musculoskeletal Disorders), and Listing 12.07 (Somatic symptom and related disorders). The ALJ then considered the severity of Dunbar’s mental impairments under the criteria in Listing 12.04 (Depressive, bipolar and related disorders), Listing 12.06 (Anxiety and obsessive-compulsive disorders), Listing 12.08 (Personality and impulse-control disorders), and Listing 12.15 (Trauma-and stressor-related disorders). At this stage, the ALJ considered the “paragraph B” criteria which required assessing Dunbar’s ability in four areas of mental function, namely to “[u]nderstand, remember, or apply information; interact with others; concentrate, persist, or maintain pace; and adapt or manage oneself.” 20 C.F.R. pt. 404, subpt. P, app. 1. The ALJ found that Dunbar had a mild limitation in understanding, remembering, or applying information; a moderate limitation in interacting with

others; a moderate limitation in concentrating, persisting, or maintaining pace; and a moderate limitation in adapting or managing oneself. (Tr. 29–30). Following step three, the ALJ assessed Dunbar’s residual functional capacity (“RFC”):

After careful consideration of the entire record, I find the claimant has the residual functional capacity to perform light work as defined in 20 CFR 416.967(b) except he [sic] can stand and/or walk for two hours in an 8-hour workday, can occasionally climb stairs and ramps, with no climbing of ladders, ropes, or scaffolds, can engage in occasional balancing as defined in the Selected Characteristics of Occupations in the Dictionary of Occupational Titles, can engage in occasional stooping, kneeling, and crouching, with no crawling, cannot perform work requiring a specific production rate, such as assembly line work, can engage in no customer-service interaction with the general public, but otherwise can engage in occasional interaction with coworkers and supervisors, and can tolerate occasional and routine changes in work setting. (Tr. 31). At step four, the ALJ found that Dunbar had no past relevant work. (Tr. 56). At step five, the ALJ considered Dunbar’s RFC, age, education, and work experience to determine Dunbar’s ability to work. The ALJ relied on a vocational expert’s testimony to conclude that there were three jobs—inspector, sorter, and assembler—that existed in significant numbers in the national economy which Dunbar could perform. (Tr. 56–57). As a result, the ALJ found that Dunbar was not disabled, as defined in the Social Security Act. (Tr. 57). Discussion The standard for judicial review of an ALJ's finding that a claimant is not disabled within

the meaning of the Social Security Act is limited to a determination of whether those findings are supported by substantial evidence. 42 U.S.C. § 405(g) (“The findings of the Commissioner of Social Security, as to any fact, if supported by substantial evidence, shall be conclusive.”); Lothridge v. Saul, 984 F.3d 1227, 1232 (7th Cir. 2021); Moore v. Colvin, 743 F.3d 1118, 1120– 21 (7th Cir. 2014) (“We will uphold the Commissioner's final decision if the ALJ applied the correct legal standards and supported her decision with substantial evidence.)”; Swiecichowski v. Dudek, 113 F.4th 751, 756 (7th Cir. 2025); Rabdeau v. Bisignano, 155 F.4th 908, 912 (7th Cir. 2025) (quoting Jarnutowski v. Kijakazi, 48 F.4th 769,773 (7th Cir. 2022)). Lincoln v. Bisignano, 2026 WL 1097727 at *2 (7th Cir. Apr. 23, 2026). A reviewing court does not “reweigh the

evidence or substitute [its] own judgment for that of the ALJ.” Id. at 1121. Instead, the court’s role is to “examine the ALJ's decision to determine whether it reflects a logical bridge from the evidence to the conclusions.” Id.; Lothridge, 984 F.3d at 1233. To warrant reversal, the burden is on the claimant to “point to evidence compelling the conclusion that the adverse disability decision lacks substantial support in the record.” Morales v.
