The opinion of the court was delivered by: Sheri Pym United States Magistrate Judge
MEMORANDUM OPINION AND ORDER
On January 13, 2012, plaintiff Arlinda Massey-Rhodes filed a complaint against defendant Michael J. Astrue, seeking a review of a denial of Disability Insurance Benefits ("DIB"). Both plaintiff and defendant have consented to proceed for all purposes before the assigned Magistrate Judge pursuant to 28 U.S.C. § 636(c). The court deems the matter suitable for adjudication without oral argument.
Plaintiff presents four specific disputed issues for decision: (1) whether the administrative law judge ("ALJ") properly assessed lay witness testimony regarding plaintiff's work at the YWCA; (2) whether the ALJ properly determined that plaintiff's lumbar impairment is not legally severe; (3) whether the ALJ properly rejected the opinions of plaintiff's treating physicians; (4) whether the ALJ properly assessed plaintiff's credibility. Memorandum in Support of Plaintiff's Complaint ("P. Mem.") at 12-21; Defendant's Memorandum in Support of Answer ("D. Mem.") at 2-9.
Having carefully studied, inter alia, the parties's written submissions, the Administrative Record ("AR"), and the decision of the ALJ, the court concludes that, as detailed herein, the ALJ failed to explain why he rejected significant probative evidence in his determination that plaintiff engaged in substantial gainful activity, and the ALJ improperly discounted plaintiff's credibility. Therefore, the court remands this matter to the Commissioner of the Social Security Administration ("Commissioner") in accordance with the principles and instructions enunciated in this Memorandum Opinion and Order.

On February 15, 2008, the Appeals Council remanded the case, ordering that the ALJ: obtain additional evidence concerning plaintiff's impairments to complete the administrative record in accordance with the regulatory standards regarding consultative examinations and existing medical evidence; evaluate lay witness testimony under the guidelines set forth in Social Security Ruling 06-3p and provide reasons for the conclusions reached; give further consideration to plaintiff's maximum residual functional capacity during the period at issue and provide rationale, with specific references to record evidence, in support of assessed limitations, and in so doing, evaluate the treating source opinion under the provisions of 20 CFR 404.1527 and Social Security Rulings 96-2p and 96-5p, explaining the weight given to such opinion evidence; and, finally, if warranted by the expanded record, obtain supplemental evidence from a vocational expert to clarify the effect of the assessed limitations on plaintiff's occupational base.
