   MEMORANDUM

Plaintiff-Appellant Matthew Taplet appeals the district court’s grant of summary judgment dismissing his suit under 42 U.S.C. § 1983, which alleged that prison officials exhibited deliberate indifference to his serious medical needs by failing to diagnose him with schizophrenia and to prescribe appropriate treatment. To prove deliberate indifference, a § 1983 plaintiff must show (1) “a serious medical need by demonstrating that failure to treat a prisoner’s condition could result in further significant injury or the unnecessary and wanton infliction of pain,” and (2) that the “defendant’s response to the need was deliberately indifferent.” Jett v. Penner, 439 F.3d 1091, 1096 (9th Cir.2006) (internal quotation marks omitted).

Taplet introduced (1) his medical records, which show that he has been diagnosed with schizophrenia in the past (though he has also been labeled a malingerer), (2) a preliminary expert report that lists the credentials of Taplet’s expert witness and articulates the standard of care for prisoners suffering from mental health conditions, and (3) Taplet’s own allegations claiming that prison officials exhibited deliberate indifference to his medical condition. Viewing the evidence in the light most favorable to Taplet, see Olsen v. Idaho State Bd. of Med., 363 F.3d 916, 922 (9th Cir.2004), we conclude that Taplet’s conflicting medical records are sufficient to demonstrate a genuine issue of material fact over whether he had a “serious medical need.”

However, Taplet has not introduced sufficient evidence to support his claim that the prison officials’ response to his alleged condition was deliberately indifferent. Although his preliminary expert report outlines the proper standard of care owed prisoners by prison officials, it explicitly did not “offer an opinion on the diagnosis or prognosis of the plaintiff,” nor did it claim that the standard of care was violated in this case. The expert explicitly stated that he had “reviewed no materials related to the plaintiff.” Only Taplet’s own allegations support his claim of deliberate indifference, and “eonclusory assertions are insufficient to avoid summary judgment.” Clouthier v. County of Contra Costa, 591 F.3d 1232, 1252 (9th Cir.2010).

Finally, the district court did not abuse its discretion by declining to give Taplet additional opportunities for discovery. Taplet never submitted an affidavit setting forth the facts he sought to uncover, that those facts existed, and that they were essential to opposing summary judgment; this failure “ ‘is a proper ground for denying discovery and proceeding to summary judgment.’” Family Home & Fin. Ctr., Inc. v. Fed. Home Loan Mortg. Corp., 525 F.3d 822, 827 (9th Cir.2008) (quoting Cal. ex rel. Cal. Dep’t of Toxic Substances Control v. Campbell, 138 F.3d 772, 779 (9th Cir.1998)).

AFFIRMED.
