SHERRY L VANDERHAAG, ) ) Plaintiff, ) ) v. ) Cause No. 1:25-cv-00545-ALT ) COMMISSIONER OF SOCIAL ) SECURITY, ) ) ) Defendant. )

OPINION AND ORDER Plaintiff Sherry L. Vanderhaag appeals to the district court from a final decision of the Commissioner of Social Security (“Commissioner”) denying her application under the Social Security Act (the “Act”) for Disability Insurance Benefits (DIB) and period of disability. (ECF 1). Vanderhaag filed her opening brief on March 17, 2026, and the Commissioner filed a response in opposition on May 28, 2026. (ECF 15, 18). On June 19, 2026, Vanderhaag timely filed her reply brief. (ECF 21). Therefore, the case is ripe for ruling. For the following reasons, the Commissioner’s decision will be AFFIRMED. I. FACTUAL AND PROCEDURAL HISTORY Vanderhaag applied for DIB and period of disability in March 2023, alleging disability beginning February 22, 2022. (ECF 7 Administrative Record (“AR”) at 21, 165-69).1 Her claim was initially denied on October 3, 2023, and denied on reconsideration on April 11, 2024. (AR 21, 69-70). On September 24, 2024, she appeared for a phone hearing before Administrative Law Judge (ALJ) Alice Blackmore. (AR 21, 36). Vanderhaag was represented by Tara Budd of

Forbes Disability Group, LLC,2 and vocational expert (VE) Kathleen Byrnes also appeared. (AR 21, 36). The ALJ issued an unfavorable decision on October 3, 2024, concluding that Vanderhaag was not disabled because she was capable of performing her past relevant work. (AR 28-29). Vanderhaag filed a request for review by the Appeals Council, which denied the request on August 5, 2025 (AR 5-7), and the ALJ’s decision became the final decision of the

Commissioner. See 20 C.F.R. § 404.981. Vanderhaag filed a complaint in this district court requesting review of the Commissioner’s final decision on October 8, 2025. (ECF 1). In this appeal, Vanderhaag argues the ALJ erred by (1) failing to account for all mental limitations in the RFC and (2) failing to account for all physical limitations in the RFC. (ECF 15 at 8, 14). On the date of the Commissioner’s final decision, Vanderhaag was fifty-two years old, had at least a high school education, and had past relevant work as a production assembler. (AR 28-29, 55, 222). Vanderhaag alleges disability due to major depressive disorder, generalized anxiety disorder, right carpal tunnel syndrome, migraines with aura, and hyperlipidemia. (ECF

15 at 5). II. STANDARD OF REVIEW Section 405(g) of the Act grants this Court the “power to enter, upon the pleadings and transcript of the record, a judgment affirming, modifying, or reversing the decision of the Commissioner …, with or without remanding the cause for a rehearing.” 42 U.S.C. § 405(g). The Court’s task is limited to determining whether the ALJ’s factual findings are supported by substantial evidence, which means “such relevant evidence as a reasonable mind might accept as adequate to support a conclusion.” Schmidt v. Barnhart, 395 F.3d 737, 744 (7th Cir. 2005)

2 Budd is an accredited non-attorney disability representative associated with Forbes Disability Group, LLC, the law firm representing Vanderhaag in this case. (See AR 21, 130-32). (citation omitted). The decision will be reversed “only if [it is] not supported by substantial evidence or if the Commissioner applied an erroneous legal standard.” Clifford v. Apfel, 227 F.3d 863, 869 (7th Cir. 2000) (citation omitted). To determine if substantial evidence exists, the Court “review[s] the entire administrative record, but do[es] not reweigh the evidence, resolve conflicts, decide questions of credibility, or

substitute [its] own judgment for that of the Commissioner.” Id. (collecting cases). “Rather, if the findings of the Commissioner … are supported by substantial evidence, they are conclusive.” Jens v. Barnhart, 347 F.3d 209, 212 (7th Cir. 2003) (citation omitted). “In other words, so long as, in light of all the evidence, reasonable minds could differ concerning whether [the claimant] is disabled, we must affirm the ALJ’s decision denying benefits.” Books v. Chater, 91 F.3d 972, 978 (7th Cir. 1996). III. ANALYSIS A. The Law Under the Act, a claimant seeking DIB must establish that she is “unable to engage in any

substantial gainful activity by reason of any medically determinable physical or mental impairment … which has lasted or can be expected to last for a continuous period of not less than twelve months.” 42 U.S.C. § 423(d)(1)(A). A physical or mental impairment is “an impairment that results from anatomical, physiological, or psychological abnormalities which are demonstrable by medically acceptable clinical and laboratory diagnostic techniques.” Id. § 423(d)(3). The Commissioner evaluates disability claims pursuant to a five-step evaluation process, requiring the ALJ to consider sequentially whether: (1) the claimant is presently employed [in substantial gainful activity]; (2) the claimant has a severe impairment or combination of impairments; (3) the claimant’s impairment meets or equals any impairment listed in the regulations as being so severe as to preclude substantial gainful activity; (4) the claimant’s [RFC] leaves [her] unable to perform [her] past relevant work; and (5) the claimant is unable to perform any other work existing in significant numbers in the national economy.

Kijakazi, 59 F.4th 293, 298 (7th Cir. 2023); 20 C.F.R. § 404.1520. “Between the third and fourth steps, the ALJ determines the claimant’s [RFC], which is the claimant’s maximum work capability.” Pufahl, 142 F.4th at 453 (citations omitted); see also 20 C.F.R. §§ 404.1520(e), 404.1545(a). “The burden of proof is on the claimant for the first four steps.” Fetting v. Kijakazi, 62 F.4th 332, 336 (7th Cir. 2023) (citation omitted). “At step five, the burden shifts to the [Commissioner] to show that there are significant numbers of jobs in the national economy for someone with the claimant’s abilities and limitations.” Id. (citation and internal quotation marks omitted). “If at any step a finding of disability or nondisability can be made, the Social Security Administration will not review the claim further.” Sevec, 59 F.4th at 298 (citation and brackets omitted).
