Prior to his work at the Minnesota Farmers Union, Commissioner Petersen spent most of his life working for his family and his own horse and farm business. He has a wide range of experience in state and federal farm policy, and travels to almost every county in Minnesota each year to fully understand how these policies affect farmers’ daily lives.

Commissioner Petersen received his associate degree from Normandale Community College and studied at both the University of Minnesota and University of Georgia. The Commissioner and his wife, Alana, live in Pine City with their two sons. The Petersens show horses around the state and have competed at the Minnesota State Fair for over 25 years.
