   MEMORANDUM.

John A. Schneck appeals pro se from the district court’s judgment dismissing his 42 U.S.C. § 1983 action arising from his termination as a patient by Sutter North Medical Foundation. We have jurisdiction under 28 U.S.C. § 1291. We review de novo, Caviness v. Horizon Cmty. Learning Ctr., Inc., 590 F.3d 806, 811-12 (9th Cir.2010), and we affirm.

The district court properly dismissed Schneck’s § 1983 action because Schneck failed to allege facts sufficient to show that defendant was acting under color of state law. See id. at 812, 815 (state action is a required element of a § 1983 claim, and mere fact that a private entity performs a function that serves the public does not make its acts state action); Ascherman v. Presbyterian Hosp. of Pac. Med. Ctr., Inc., 507 F.2d 1103, 1104-05 (9th Cir.1974) (private hospital’s receipt of public funds and tax exempt status as a charitable organization insufficient to establish state action).

Schneck’s contentions regarding judicial bias are unpersuasive. See Taylor v. Regents of the Univ. of Cal., 993 F.2d 710, 712 (9th Cir.1993) (per curiam) (adverse rulings alone are insufficient to demonstrate judicial bias).

AFFIRMED.
