From the official site:

Dad: John, ER doctor

Mom: Kathy

Children: Matt, 11, Mike, 10, Andrew, 7, Ryan, 5

The Wiesenfarth kids are actively involved in soccer, baseball, swimming, piano lessons, church, friends and most uniquely, chicken chasing (yes, you read that right chicken chasing!). Being an emergency room doctor, Dad works around the clock, so the role of Household CEO is left for Mom to fulfill. While Dad occasionally helps with cooking, shopping, and homework, Mom does most of it, in addition to the household budgeting. Sounds like Dad will need help stat!
