MEMORANDUM OPINION AND ORDER
Plaintiff, who is proceeding with retained counsel, brings this action for judicial review of a final decision of the Commissioner of Social Security under 42 U.S.C. § 405(g). Pursuant to the written consent of all parties, this case is before the undersigned as the presiding judge for all purposes, including entry of final judgment. See 28 U.S.C. § 636(c). Pending before the court are plaintiff's motion for summary judgment (Doc. 14) and defendant's cross-motion for summary judgment (Doc. 18).
Plaintiff applied for social security benefits on December 18, 2007. In the application, plaintiff claims that disability began on January 1, 1998. Plaintiff claims that disability is caused by a combination of mental impairments. Plaintiff's claim was initially denied. Following denial of reconsideration, plaintiff requested an administrative hearing, which was held on July 7, 2009, before Administrative Law Judge ("ALJ") Daniel G. Heely. In a November 23, 2009, decision, the ALJ concluded that plaintiff is not disabled based on the following relevant findings:
1. The claimant has the following severe impairments: depression and anxiety;
2. The claimant does not have an impairment or combination of impairments that meets or medically equals an impairment listed in the regulations;
3. The claimant has the residual functional capacity to perform a full range of work at all exertional levels with the following non-exertional limitations: she can perform work involving simple routine tasks with occasional public contact, simple reading and writing requirements, and no complex, technical, or scientific concepts; and
4. Consideration the claimant's age, education, work experience, and residual functional capacity, there are jobs that exist in significant numbers in the national economy that the claimant can perform.
After the Appeals Council declined review on November 9, 2010, this appeal followed.
The court reviews the Commissioner's final decision to determine whether it is:
(1) based on proper legal standards; and (2) supported by substantial evidence in the record as a whole. See Tackett v. Apfel, 180 F.3d 1094, 1097 (9th Cir. 1999). "Substantial evidence" is more than a mere scintilla, but less than a preponderance. See Saelee v. Chater, 94 F.3d 520, 521 (9th Cir. 1996). It is ". . . such evidence as a reasonable mind might accept as adequate to support a conclusion." Richardson v. Perales, 402 U.S. 389, 402 (1971). The record as a whole, including both the evidence that supports and detracts from the Commissioner's conclusion, must be considered and weighed. See Howard v. Heckler, 782 F.2d 1484, 1487 (9th Cir. 1986); Jones v. Heckler, 760 F.2d 993, 995 (9th Cir. 1985). The court may not affirm the Commissioner's decision simply by isolating a specific quantum of supporting evidence. See Hammock v. Bowen, 879 F.2d 498, 501 (9th Cir. 1989). If substantial evidence supports the administrative findings, or if there is conflicting evidence supporting a particular finding, the finding of the Commissioner is conclusive. See Sprague v. Bowen, 812 F.2d 1226, 1229-30 (9th Cir. 1987). Therefore, where the evidence is susceptible to more than one rational interpretation, one of which supports the Commissioner's decision, the decision must be affirmed, see Thomas v. Barnhart, 278 F.3d 947, 954 (9th Cir. 2002), and may be set aside only if an improper legal standard was applied in weighing the evidence, see Burkhart v. Bowen, 856 F.2d 1335, 1338 (9th Cir. 1988).
In her motion for summary judgment, plaintiff argues: (1) the ALJ failed to state specific and legitimate reasons for not crediting the opinion of plaintiff's treating physician, Dr. Smith; and (2) the ALJ failed to state sufficient reasons for accepting the opinions of one-time examining physicians, Drs. Wakefield and Richwerger. The weight given to medical opinions depends in part on whether they are proffered by treating, examining, or non-examining professionals. See Lester v. Chater, 81 F.3d 821, 830-31 (9th Cir. 1995). Ordinarily, more weight is given to the opinion of a treating professional, who has a greater opportunity to know and observe the patient as an individual, than the opinion of a non-treating professional. See id.; Smolen v. Chater, 80 F.3d 1273, 1285 (9th ...
