College and Amateur
McMahen played college soccer at Michigan State University from 2001 to 2005. He finished his career with 26 goals and 28 assists, coming out of the midfield; the latter was good enough for second all-time in school history. While at Michigan State, McMahen garnered many accolades including All Big Ten three times, and All America as a senior. During his college years he also played with the Michigan Bucks in the Premier Development League where he was an All League Performer.
He made his professional debut on July 12, 2006 in the Lamar Hunt U.S. Open Cup match against Des Moines Menace, playing the full game. He also made an appearance on July 1, 2008 in the same competition, starting the match against Carolina Railhawks.
McMahen was waived by the Wizards on September 5, 2008, having never registered a single minute in a Major League Soccer game. He joined Austin Aztex of the USL First Division for the 2009 season, but was released by the Aztex at the end of the year.
