Mountain Ridge Lacrosse is a member of the Arizona Lacrosse League (ALL). The ALL, a 501(c)(3) organization, is the official league for high school lacrosse in the state of Arizona. The ALL requires all member clubs to be nonprofit per its bylaws. The ALL requires players to play on either the lacrosse team nearest the student’s school or on the nearest lacrosse team to the student’s home address by Google Maps. As such, the Mountain Ridge Lacrosse Club represents students from Mountain Ridge, Barry Goldwater, Deer Valley, Glendale Prep, Joy Christian, Liberty, Sandra Day O’Connor, and Sunrise Mountain high schools in Glendale, Peoria, and Phoenix, Arizona.
