OPINION OF THE COURT

Tommie Lou Rios appeals from the District Court’s order entered on January 22, 2002, upholding the Social Security Administration’s determination of her onset date of disability benefits. We will affirm.

Tommie Lou Rios, a college graduate with experience as an accountant and fi*100nancial consultant, suffers from a number of ailments, including the serious residual effects of an injury to her right index finger, arthritis in her right knee, high blood pressure, heart problems, mild dementia, and a depressive disorder. In 1995, Rios filed an application with the Social Security Administration for disability benefits, alleging a disability onset date of July 23, 1994. After a hearing, the ALJ denied Rios’s application, finding that Rios was not disabled during the relevant time period. Rios sought review of the decision in the District Court, an action that was ultimately remanded back to the Commissioner because the tape recording of the administrative hearing could not be located for transcription. A new hearing was held on July 10, 2000, at which the ALJ concluded that Rios became disabled on December 18, 1998, and Rios was awarded benefits as of that date. On December 28, 2000, the decision of the ALJ became the final decision of the Commissioner, and Rios again sought review in the District Court, challenging the ALJ’s determination of her disability onset date. On January 22, 2002, the District Court affirmed the decision of the Commissioner. This timely appeal followed.

We have jurisdiction under 28 U.S.C. § 1291 and 42 U.S.C. § 405(g). Although Rios alleges that the ALJ committed a wide variety of errors, we can find no basis upon which to disturb the ALJ’s conclusions. Our review is limited to ensuring that the ALJ’s decision was supported by substantial evidence, which is “more than a mere scintilla,” and “means such relevant evidence as a reasonable mind might accept as adequate to support a conclusion.”1 Richardson v. Perales, 402 U.S. 389, 401, 91 S.Ct. 1420, 28 L.Ed.2d 842 (1971); see also Burns v. Barnhart, 312 F.3d 113, 118 (3d Cir. 2002); Fargnoli v. Massanari, 247 F.3d 34, 38 (3d Cir. 2001).

Rios has continually maintained that the onset date of her disability was in July of 1994. That claim was rejected in both hearings before the ALJ, and there is substantial evidence in the record that supports the ALJ’s conclusions. There is no persuasive evidence — medical or otherwise — suggesting that Rios’s various ailments prevented her from working in her previous capacity prior to the onset date established by the ALJ.2 Rios’s previous work as an accountant and financial con*101sultant was relatively undemanding physically, and the medical evidence provides no indication that her physical impairments were so severe as to prevent her from performing that work. Similarly, there is no medical evidence to suggest that Rios’s mental impairments were disabling prior to the onset date established by the ALJ, and it in fact appears that Rios concedes the propriety of the ALJ’s findings on that score. In short, the ALJ’s findings were supported by substantial evidence.

Accordingly, the order of the District Court wifi be AFFIRMED.
