Centercare has been serving downtown Phoenix and the historic districts for over twenty years. Dr. Gary Steen began the practice in 1991 after many years working in international public health and in private practice elsewhere in Phoenix. Its original location was in the Arizona Center in downtown Phoenix. Centercare was designed as an advanced general practice which targeted working and professional adults. That has remained its focus. The practice grew substantially over the years, as did all of downtown. As the Suns’ arena, Chase Field, Cityscape and ASU Downtown appeared, access for patients gradually became more difficult and Centercare made plans to move.
