Kathryn Stiles grew up in the Los Angeles area. She attended Dartmouth College and USC Medical School. Following her three year pediatric residency at Children's Hospital of Los Angeles she joined Agoura West-Valley Pediatrics and has been there ever since. She has three sons: Nick, Greg and Erik. Nick plays football at the University of Arizona. Greg plays soccer for UCLA and Erik is a senior in high school hoping to follow in his brothers' footsteps. Needless to say, much of her spare time is spent on the sidelines of one game or another.
