Bill Matthias was born in Columbus, Wisconsin, and grew up in Madison. He began his studies at the University of Wisconsin–Madison as a preforestry major and rekindled his interest in the pine, oak, and lake regions of northwest Wisconsin when he became the superintendent of Northwood School District in Minong in 1975. While superintendent, Matthias launched the teenage firefighting crews at Northwood High School and battled the Five Mile Tower Fire of 1977 for 50 hours. He and his wife, Karen, spend their winters in Florida and each spring return to the Wisconsin Northwoods, where Matthias is a charter member of the Wascott Volunteer Fire Department.
