MEMORANDUM

Bryant Penigar appeals from a district court judgment dismissing with prejudice his 42 U.S.C. § 1988 claims against various San Bernardino County Deputy Sheriffs identified in his first amended complaint only as “Does,” and granting summary judgment to the County on his Monell claim. We have jurisdiction under 28 U.S.C. § 1291 and affirm.

1. Under Federal Rule of Civil Procedure 16(b), Penigar was required to show good cause why he had not amended his complaint to name the actual deputies he sought to sue within the time limit established by the district court’s scheduling order. The district court did not abuse its discretion in finding that Penigar had not met that burden, because Penigar failed to make any showing of good cause. Johnson v. Mammoth Recreations, Inc., 975 F.2d 604, 607-09 (9th Cir.1992). Therefore, the district court properly dismissed his § 1988 claim against the unnamed deputies.

2. Penigar claimed his civil rights were violated as a result of inadequate training and supervision policies of the San Bernar-dino Sheriffs Department on the use of tasers. See Monell v. Dep’t of Social Servs., 436 U.S. 658, 694 , 98 S.Ct. 2018 , 56 L.Ed.2d 611 (1978). In support of its motion for summary judgment, the County submitted evidence that its training and supervision policies were reasonable. Pe-nigar did not offer any evidence to the contrary, nor did he designate an expert on the subject. Penigar also failed to ask the district court to extend the discovery deadline until after it had passed. Because Penigar failed to demonstrate the presence of an issue of genuine material fact for trial, summary judgment was appropriate.

AFFIRMED.
