Benjamin Robert Olsen (born May 3, 1977) is an American soccer executive, coach and former player who is the head coach of Houston Dynamo in Major League Soccer (MLS). He is best known for his long-term association with D.C. United, first as a player then as a coach. Olsen was formerly the president of Washington Spirit in the National Women's Soccer League (NWSL).

Born in Middletown, Pennsylvania, Olsen grew up playing for FC Delco, an elite club program near Philadelphia. He then played for Virginia Cavaliers men's soccer and was named 1997 Soccer America Player of the Year.

Olsen spent the vast majority of his professional career in the United States with D.C. United in Major League Soccer, and also had a loan spell with English side Nottingham Forest. He joined United straight out of college, and over the course of 12 seasons, Olsen made 221 appearances, scoring 29 goals and making 49 assists. During that time he won two MLS Cup titles, two MLS Supporters' Shields and one U.S. Open Cup. His individual honors include two-time MLS All-Star, 1998 MLS Rookie of the Year, MLS Cup '99 MVP and 2007 MLS Best XI.

Olsen also earned 37 caps with the United States men's national team, winning the 2005 CONCACAF Gold Cup and representing the United States at the 2006 FIFA World Cup.

Olsen announced his retirement from professional competition in 2009.

Youth and college soccer

Olsen grew up in Middletown, Pennsylvania. He played his youth soccer for premier team FC Delco, where he was inducted into the club's Hall of Fame. Olsen attended Seven Sorrows of the Blessed Virgin Mary School and Middletown Area High School, where he was named Parade magazine's National High School Player of the Year in 1993.

Olsen was motivated to play college soccer at the University of Virginia because the team had just won four NCAA Division I Championships and was coached by Bruce Arena, who had previously coached Olsen when he was 14 to 15 years old. While at UVA the Cavaliers achieved two Final Fours and won two ACC Men's Soccer Tournament titles with Olsen being honored as the ACC Tournament MVP in 1997. In that same year the Cavaliers advanced to the NCAA final after Olsen scored two goals to lift the Cavaliers 3–1 over the St. Louis Billikens in the semifinal round. In his three-year career he tallied 34 goals, 41 assists and 109 total points. During his junior year he was named the 1997 Soccer America Player of the Year.

Professional career

Olsen entered the league as a Project-40 player, and was allocated to D.C. United on December 27, 1997, shortly after finishing his junior season at UVA. In 1998 Olsen excelled as a right midfielder with United. During his inaugural season he earned a starting spot and scored 4 goals and made 8 assists. These accomplishments earned him the 1998 MLS Rookie of the Year Award and supported the team as it won the 1998 CONCACAF Champions Cup and 1998 InterAmerican Cup.

During Olsen's second season with United he scored 5 goals and made 11 assists over 26 games, which contributed to United earning the 1999 Supporters' Shield on the way to winning MLS Cup '99. It was United's third MLS Cup victory in the first four years of the league. Olsen, the game's MVP, was especially happy to win the championship game after losing MLS Cup '98 to the Chicago Fire.

Olsen's third season began well, but a collision with Chicago Fire goalkeeper Zach Thornton caused an ankle injury that kept Ben out of much of the second half of the season, limiting him to 13 starts and only 1 goal and 3 assists on the year. After he recovered from the ankle injury in late 2000, Olsen was loaned by United to Nottingham Forest of the English First Division, where he immediately impressed and soon became a fan favorite. As a transfer became increasingly likely, Olsen severely fractured his ankle during a December game. During his 18-month absence Olsen required four surgeries and continuous rehabilitation. He finally returned in July 2002 and was able to finish the season with 7 starts and 10 games played.

In 2003 Olsen completed a full season with United for the first time in four years. He started 26 games for the team, while scoring 4 goals and making 7 assists. Although his speed was limited due to his injuries and surgeries, Olsen was able to adapt to a new position as a center midfielder. It was here that Olsen spent his time in 2004 as well, starting 25 games for United, scoring 3 goals and 4 assists. He scored 2 goals and 4 assists in 2005.

D.C. United needed Olsen back at wide midfielder for the 2007 season, and he responded well. He served as Captain when Jaime Moreno was away on national team duty, scored his first career hat trick in a 4–2 win over New York Red Bulls on June 10, and enjoyed his best season in MLS. He ended the year with seven goals and seven assists and was named to the MLS Best XI team. Olsen had surgery on both of his ankles in Baltimore on November 5, 2007.

Ankle problems again sidelined Olsen for the beginning of the 2008 MLS season, and there was speculation that his career was in jeopardy. Despite said problems, Ben Olsen was able to make one MLS appearance against the Los Angeles Galaxy on June 28, 2008. The crowd greeted him with the loudest ovation of the day and a tifo that read "Ben Olsen" and "Heart Of A Lion". After playing just 15 minutes Olsen responded to the media by stating, "It wasn't great; I was like a wounded animal out there." On July 7, 2008, Olsen underwent another ankle surgery.

Olsen was able to continue his career during the 2009 season in a defensive midfield role, scoring the tying goal in stoppage time of a 1–1 tie with the New England Revolution. On May 2, 2009, Olsen injured himself during a game against FC Dallas, which led him to be substituted out during the second half. After skipping two matches he played against Chivas USA at the Home Depot Center on May 16, 2009. Six minutes into that match he aggravated his hamstring.
