A. Overview of Administrative Proceedings
On January 30, 2007, Plaintiff applied for Disability Insurance Benefits pursuant to Title II of the Social Security Act (the "Act") (Administrative Record, "AR," at 125-26.) Plaintiff's application was denied on initial review and again on reconsideration. (AR at 64, 74.) Thereafter, Plaintiff requested a hearing before an Administrative Law Judge (the "ALJ"). On May 4, 2009, Plaintiff appeared with counsel and testified before the ALJ. (AR at 26-63.) In a decision dated September 22, 2009, the ALJ found that Plaintiff was not disabled from June 6, 2005 through February 21, 2008, however, beginning February 21, 2008, Plaintiff was disabled under the Act. (AR at 10-23.) The ALJ's decision became the final decision of the Commissioner when the Appeals Council denied Plaintiff's request for review. (AR at 3-5.) Plaintiff then commenced this action for judicial review pursuant to 42 U.S.C. § 405(g).
The ALJ determined that Plaintiff was not disabled prior to February 21, 2008, however, became disabled on that date and has continued to be disabled. Plaintiff does not challenge the ALJ made any errors in evaluating medical evidence, hearing testimony or in making his residual functional capacity finding. Plaintiff only challenges the ALJ's finding that Plaintiff could perform work in the national economy prior to February 21, 2008, based on Plaintiff's residual functional capacity finding. Thus, the Court summarizes the ALJ's findings to the extent they are necessary to this appeal. Relevant to this appeal, the ALJ determined that:

2. Between June 6, 2005 and February 21, 2008, 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(20 C.F.R. 404.1520(d), 404.1525 and 404.1526);
3. Prior to February 21, 2008, Plaintiff had the residual functional capacity to lift and carry no more than 10 pounds frequently and 20 pounds occasionally.
