Youth and college
Soehn was born to immigrant parents. His parents moved to the United States from Germany, but his father was born in Romania. Soehn began playing soccer with the Chicago Kickers when he was four. He attended Forest View High School. He attended Western Illinois University from 1984 to 1987. In 2003, Western Illinois inducted Soehn into its Athletics Hall of Fame.
Soehn signed with the Wichita Wings of Major Indoor Soccer League from 1988 to 1992. He moved to the Denver Thunder of the National Professional Soccer League (NPSL) for the 1992-1993 season before returning to the Wings in 1993 which were now playing in the NPSL. He remained with the Wings until 1996. In 1995, he played the summer indoor season with the Las Vegas Dustdevils of the Continental Indoor Soccer League (CISL).
In addition to playing indoor soccer, Soehn played with the Colorado Foxes of the American Professional Soccer League (APSL) in 1992, 1993 and 1994. The Foxes went to three consecutive APSL championship games those three seasons. They won the 1992 and 1993 titles, but lost to the Montreal Impact in 1994.
Soehn played four years in MLS after being drafted by the Dallas Burn in the second round of the 1996 MLS Inaugural Player Draft. He missed the 1996 season with the injury, but played for the Burn in 1997. In 1998, he began the season with the Burn, but was traded to the Chicago Fire after fourteen games. He remained with the Fire until he retired from playing in 2000. During his time with Chicago, he was a member of the Fire's three championship teams (MLS Cup 1998, U.S. Open Cup 1998 and 2000).
After retiring as a player, he became an assistant coach to Bob Bradley at the Fire and then moved to DC United to become Peter Nowak's top assistant in 2003. During his time as the top assistant, DC United won MLS Cup in 2004, and a Supporters Shield in 2005. On December 21, 2006, Soehn replaced Nowak as the head coach at United.
On November 3, 2009, it was announced that Soehn had withdrawn himself for consideration for a contract renewal, ending a three-year reign that included a Supporters Shield in 2007, an Open Cup in 2008 and Open Cup Runner-Up in 2009.
On 19 January 2010, Soehn was given the job as Director of Soccer Operations by Canadian soccer club Vancouver Whitecaps FC. On 30 May 2011 it was announced that he would take over as head coach of the Vancouver Whitecaps, after Teitur Thordarson was let go by the club. After the 2011 season ended, Soehn stepped down from the head coaching role in favor for Martin Rennie and reclaimed his former position as Director of Soccer Operations.
On November 15, 2012, it was revealed that Soehn and Vancouver Whitecaps FC had mutually parted ways.
In addition to his professional coaching, Soehn serves as the director of his boyhood club, the Chicago Kickers.
