A Day in the Life of Pediatric Surgeon Dr. Peter Yu

5:00 a.m.: Alarm rings. I hit snooze once, for an additional 9 minutes of peace. Then it is time to get up and at ’em. In the dark, I attempt to avoid injuring myself on the various toys that are strewn about the house–one of the hazards that comes with raising young children. I start the coffee maker, brush my teeth, shave, get dressed and kiss my slumbering family good-bye. Then it is off to swim practice.
