Ken is a cranky but lovable HMO doctor juggling medicine and parenting who realizes that even when he's right, his unorthodox approach is often wrong. Allison, his wife and a therapist, helps keep him in check while juggling responsibilities with their two kids -- Dave, their youngest, is always making things interesting with his quirky attitude, plus their teenage daughter, Molly, keeping them on their toes. Meanwhile at the clinic, Dr. Ken's staff includes his loyal, but oh-so-irritating staff, including a sharp tongued receptionist; a faithful nurse who is a confidante and partner-in-crime; a sweet, naive resident who's relentless optimism and quest for romance are a constant source of curiosity and irritation; and his nemesis, the hospital administrator, who never misses a chance to put the screws to Dr. Ken and his staff.
