USTA Southern California, formerly known as the Southern California Tennis Association, is one of 17 sections that make up the United States Tennis Association.[1] Each non-profit section represents various geographic locations around North America with the goal to support players and promote the growth of tennis across the United States.[2][3] USTA Southern California has 40,000 members and more than 2,000 member organizations or tennis facilities. It consists of a staff of 32 and is headquartered on the campus of the University of California Los Angeles in Westwood, California, home of the Los Angeles Tennis Center.[4] Currently, Southern California's top junior tennis players train in Carson, California, the home to the USTA Training Center – West.[5] The Southern California section includes areas from the coast of San Diego to the south to the Central Coast to the north extending to San Luis Obispo County, east to Bakersfield, and including the Inland Empire and the Coachella Valley. USTA Southern California works with various organizations such as the City of Angels to provide free adaptive and wheelchair tennis lessons throughout Southern California.[6] Southern California resident Brad Parks is largely credited with starting the sport of wheelchair tennis in the mid-1970s after suffering a skiing accident.[7]
