In his first 16 years as the Cobber men's head coach he has put together three of the four winningest seasons in Cobber history. Heading into the 2007-08 campaign, Siverson has a 171-225 overall record.

The 2004-05 squad led the nation in 3-point field goal percentage. They also made the conference playoffs for the third time in the past five years.

In 2003-04, the team finished the year with an 18-8 overall mark and a 14-6 record in conference play. Both win totals were in the top five in school history. As a team, Concordia finished the '03-'04 campaign by being ranked in the top ten in Division III in field goal percentage, free throw percentage and 3-point field goal percentage - a first in Cobber men's basketball history.

The 1995-96 squad went 16-4 in the MIAC, captured the MIAC playoff championship and was 21-6 overall. The 1995-96 Cobbers earned a first-ever NCAA men's basketball tournament bid. The 21 wins is a school record.

In the 1996-97 season, the team finished by winning 10 of their last 12 games, and finished in the top four of the conference. That marked the third straight season that Concordia had accomplished that feat. The final winning string also established Siverson at the top of the charts in all-time basketball coaching wins at Concordia.

His 1994-95 team went 18-7 (matching the second best win total in school history).

He served as an assistant coach for the Running Cobbers from 1978-1984, during which time the Cobbers captured two MIAC titles. In 1984 Siverson took over as head coach of the Cobber women's program and guided them to four MIAC titles, the 1988 NCAA Division III National Championship and seven NCAA tournament appearances. He was NCAA Division III National Coach of the Year in 1988. He became head coach of the Running Cobber program in 1991.

Siverson was raised in Casselton, ND, and later moved to Spokane, WA, where he graduated from high school. He received his B.A. degree from Yankton College in 1978 and earned honors for both academic and athletic achievements.

Siverson also serves as an assistant for the Cobber women's golf coach and teaches in the Health and Physical Education Department.

He and his wife Bonnie, and their two sons, Tyler and Jordan, live in south Moorhead.
