My family and I LOVE mountainside fitness - Peoria location. I love all mountainside fitness locations, but Peoria just feels like home. I’ve been a member for over 5 years. They are the only gym facility I trust to take care of my kids while I work out, I drive 30 minutes after moving just to get to this location. Clean, friendly staff, and even members/staff feel like family. Mix of new comers and old members, but never any judging. The personal trainers will work with injuries, rehab, and all different kinds of fitness goals. They also work with certain types of insurance AND have first responder discounts.

Group fitness instructors are great but some of the front desk staff and the membership services employees are less than understanding. Very rigid and not willing to work on the spot with customers. I will be telling my Arizona family not to use this gym.

Bailee was very informative regarding my questions concerning the facility. equipment and registration process. As a new member my expectation is that the facility and personnel will match her depiction.
