Kevin Payne has been D.C. United's lead executive since the club was first created in 1996.
Kevin Payne, the only chief executive and president that D.C. United has ever known, stepped down on Tuesday.
"To the players, coaches, co-workers and fans, I can only say thank you so much for the great privilege of having been part of the D.C. United family," Payne said in a statement. "I'm very excited about the next phase of my life, and very excited about the next phase for D.C. United, as well."
Kevin Payne has been with D.C. United since its inception in 1996, when he was part of the original investment group. During his tenure, the club won four MLS Cups and two U.S. Open cups.
Most recently, the club advanced to the conference finals, where they were eliminated by the Houston Dynamo.
Ownership of the club has changed hands in recent years. William Chang, one of the primary investors in the San Francisco Giants, acquired full control of the team in 2009. This summer, Chang was joined by two minority owners who are pushing the construction of a new stadium for the team.
Payne will be headed to fellow MLS club Toronto FC, according to the Washington Post.
