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.

When the office celebrates a promotion for Clark, Ken is oblivious since he lives in his own world.. it's the last straw for Clark dealing with Ken's selfish ways. Clark writes a fake complaint comment card about Ken, so he's forced to attend a training seminar for better bedside manners, which leaves Allison at home to have dinner with Ken's parents.

Pat wants everyone to start working on Saturdays, so the workers in the office ask Ken to talk Pat out of it. When Ken visits Pat at home, he's shocked to find out he's living in a boat in the driveway. After Pat explains he's going through a divorce but still loves his wife, Ken thinks they've had a bonding moment. Meanwhile, Dave is given a new nickname at school and it brings up bad memories for Allison.
