Now Open Our 22nd Location in San Tan
On February 22nd, we proudly opened the doors to our newest home for health and community — Mountainside Fitness San Tan, officially becoming our 22nd location in Arizona.
For 35 years, Mountainside Fitness has been committed to one mission: keeping the Valley healthy. What started as a single club has grown into Arizona’s largest locally owned fitness company — and we’re just getting started.
San Tan Valley, welcome to the Mountainside family.
