Leon has been a resident of Bowie, District 4, since 2003. He quickly discovered a passion for coaching and working with youth. He began coaching baseball and basketball for the South Bowie Boys and Girls Club. He then served the South Bowie Boys and Girls Club (SBBGC) as both baseball commissioner and Athletic Director, while also serving on the SBBGC's Community Recreation Committee. Leon and the board worked successfully to acquire much needed dollars both from the city of Bowie and the State of Maryland—working with Senator Douglas Peters—to build a concession stand at the Church Road football field. Leon also worked successfully with Bowie City Councilman Todd Turner on adding much needed earmarks to the city's recreation budget.
In 2012, Leon founded the Bowie Elite Baseball Club, a 501(c)(3) organization located in Bowie, Maryland, that promotes youth baseball for players in the DC Metropolitan area. The organization comprises players from Prince Georges, Montgomery, Charles, and Calvert counties, in Maryland, and from the District of Columbia. Since its inception, the Club has served more than 500 young men and their families. The Bowie Elite Baseball Club plays its home games in Bowie, Maryland, and travels throughout Maryland and to tournaments throughout the mid-Atlantic region. The mission of the club is “through baseball, we have a positive impact on the lives of our area youth, their families, and the community.” Leon currently coaches a Varsity-age high school team for Bowie Elite.
Leon served as a valuable member on the Bowie Election Commission in 2008, where the body decided to recommend to change city council terms from two years to four years.
Leon is also a member of Alpha Phi Alpha Fraternity, Inc. Leon has served the fraternity as President of a local Washington, DC, chapter, as well as serving as the Mid-Atlantic District Director for Washington, DC, Maryland and Delaware.
