The opinion of the court was delivered by: Sheri Pym United States Magistrate Judge
MEMORANDUM OPINION AND ORDER
On December 27, 2011, plaintiff Mario R. Trujillo filed a complaint against defendant Michael J. Astrue, seeking a review of a denial of Disability Insurance Benefits ("DIB") and Supplemental Security Income ("SSI") benefits. 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 parties' briefing is now complete, and the court deems the matter suitable for adjudication without oral argument.
Two issues are presented for decision here: (1) whether the Administrative Law Judge ("ALJ") properly considered the evidence of a medically determinable severe mental impairment; and (2) whether the ALJ properly evaluated the opinion of plaintiff's treating physician. Pl.'s Mem. at 15-19, 19-22; Def.'s Mem. at 2-8, 8-10.
Having carefully studied, inter alia, the parties' written submissions and the Administrative Record ("AR"), the court finds that, as detailed herein, the ALJ properly evaluated the medical evidence and determined that plaintiff does not suffer from a severe mental impairment. In addition, the ALJ properly rejected the opinion of plaintiff's treating physician with respect to the extent of his physical impairment. The court therefore affirms the Commissioner's decision denying benefits.

Plaintiff alleged that he has been disabled since January 31, 2007 due to diabetes, hypertension, bodily pain, and mental problems. Id. at 57, 153.
