Soderberg played basketball in college at Ripon College from 1980 to 1982 before he transferred to University of Wisconsin–Stevens Point, playing at Stevens Point from 1982 to 1984 under head coach Dick Bennett, and with Terry Porter (who later became player and eventually a head coach in the National Basketball Association).

The 1984 team made it all the way to the championship game of the NAIA Tournament before falling 50–48 to Fort Hays State University.

Three games into the 2000–01 campaign, the Badgers (coming off a Final Four appearance in 2000) saw their head coach, Dick Bennett retire.

However, the team lost in the first round of the NCAA tournament to Georgia State University, considered a major disappointment to many Badger fans.

Soderberg accepted an assistant post at Saint Louis University under head coach Lorenzo Romar.

On April 17, 2007 St. Louis sports station KFNS announced that Soderberg had been dismissed as men's basketball coach.

Lindenwood's defense held St. Catharine ten points below its season average and forced 13 turnovers in the game.

Competing as an independent, Lindenwood finished the season with a 26–3 record and was invited to the NCAA's Division II Transitional Tournament in Spearfish, South Dakota.

Soderberg led them to the Division II Transitional National champions by defeating Minot State and Sioux Falls to end the season with a final 28–3 record.
