Captain Stottlemeyer (Ted Levine) is Adrian Monk's former partner and boss, the longtime friend who was ultimately forced to let Monk go from the San Francisco Police Department when his obsessive-compulsive disorder began to dangerously interfere with his work.

Though often annoyed and baffled by his friend's behavior, Stottlemeyer recognizes Monk's brilliance and frequently calls upon his old partner to provide unique insight into cases that have San Francisco's finest stumped. And although it can drive Stottlemeyer crazy to know that he'll never be quite as brilliant a detective as Monk, the divorced father of two remains a loyal friend.
