Marc Sonnen serves as Assistant Coach for University of Northern Iowa's Men's Basketball program in Cedar Falls, Iowa. A prolific scorer who played for the Panthers from 2009 to 2013, Sonnen returns to UNI after three seasons coaching at the Division II level. Sonnen spent the two seasons at Drury University in Springfield, Missouri on the coaching staff of fellow UNI basketball alum Chris Foster.
Helping the Panthers to 29 wins in two years, he helped develop five All-Great Lakes Valley Conference (GLVC) athletes, including 2025 Second Team All-GLVC guard Logan Applegate, a pair of all-conference defensive team honorees in Colin Hardrick and Brock Wakefield, as well as All-Freshman Team member Jouk Riak in 2024. Prior to his time in southern Missouri, Sonnen ventured north to his home state of Minnesota, spending the 2022-23 season at Minnesota Duluth. In his lone season with the Bulldogs, Sonnen helped UMD post a 26-10 record, finishing 16-6 and placing third in the Northern Sun Intercollegiate Conference’s (NSIC) North Division. After a run to the NSIC Tournament championship game, the Bulldogs, led by All-NSIC performers Drew Blair and Charlie Katona, won three games to win the NCAA Central Region title and advance to the NCAA Division II Elite Eight.
