Personal Information

Dr. Schoonmaker is married to Kimberlee and together they have three girls: Jenna, Amanda and Lauren. They also have four cats, a dog, three rabits, and they raise 2-3 sheep every year for the county fair. Jon and Kimberlee grew up in Wisconsin; he grew up on a hobby beef/sheep farm outside of Madison, WI. Dr. Schoonmaker likes to snow ski, fish, and golf. He coaches his daughter's soccer team, and is related to Tony Dow (Wally from Leave it to Beaver), but Jon has never met Tony.
