Mike Fossum has been a member of the Wisconsin Lutheran College football coaching staff longer than any other coach, entering his 21st season as an assistant for the Warriors. Fossum serves as WLC's offensive line coach and director of football operations.
In the 17 seasons the Warriors have been affiliated with a conference, Fossum has developed 22 all-conference offensive linemen, including at least one every year since 2002. Last season, Connor Young received Honorable Mention recognition.
Wisconsin Lutheran won the league’s rushing title in 2009 behind Fossum's offensive line and has ranked second four times since. In 2014, running back Mike Reeves finished his Warriors career tied for the all-time lead in rushing touchdowns (23) and as the sole leader in average yards per carry (5.62).
WLC produced two of the conference's top three running backs in 2011, when Jesse Muldrow and Donavin Tucker combined to create a formidable duo in the backfield. Fossum's offensive line also helped pave the way for Tucker to break the single-game rushing record with his 220-yard performance against Rockford that season. The Warriors offensive line also led the way in a 42-20 win over Minnesota-Morris in which WLC had three players rush for over 100 yards.
Fossum's offensive line played a crucial role when former running back Matt Kehl broke the MIAA career rushing record in 2006. Kehl, who was inducted into the WLC Athletics Hall of Fame in 2015, finished his career with 3,190 career rushing yards.
Fossum had five seasons of experience at the NCAA Division II and III football ranks prior to his appointment at Wisconsin Lutheran. His most recent assignment was as an assistant coach for two years (1997-1998) at Division I-AA South Dakota State University for head coach John Stiegelmeier. There he worked primarily with the defensive secondary, and assisted with special teams and scouting. For three seasons (1994-1996), Fossum coached the defensive line at his alma mater, St. Olaf College in Northfield, Minnesota. During his stint, six linemen earned all-conference honors and one was selected to the all-region team.
An offensive lineman while at St. Olaf, Fossum was an all-conference selection under former head coach Don Canfield and earned the team's Most Inspirational Leadership Award his senior season. During his prep days at Black River Falls High School, Fossum played football for Warren Rosin, a member of the Wisconsin Football Coaches Association Hall of Fame.
Fossum earned a bachelor's degree in chemistry from St. Olaf (1994), a master's degree in athletic administration from South Dakota State (1998), and a master's in business administration from the University of Phoenix (2004).
Fossum, who is actively involved in summer camps throughout the Milwaukee area, is a member of both the American and Wisconsin Football Coaches Association. He and his wife, Astrid, have two sons, John and Will, and a daughter, Julia. The family resides in Milwaukee.
