It all started with an idea. An idea to be the friendliest gym in town. To know our Members'​ names. To offer free towel service, even if that meant doing laundry until two in the morning. This was the beginning of Mountainside Fitness.In 1991, Tom Hatten began Mountainside Fitness (then named Mountainside Gym) while a junior at Arizona State University. Together with family and friends, he brought his dream to life. From welding gym equipment to painting walls to selling memberships, the early years were true sweat equity in every sense of the word. With 300 pre-sold memberships, Mountainside opened its doors. It was a small 4,800 sq. ft. fitness center in Mountainside Plaza located in Ahwatukee. Our signature was free towel service to everyone. However, this would have been a lot easier if Tom could have afforded a washer and dryer at the gym, but he made it work. It was worth it to be building a business and community he believed in. To show appreciation to the Members, Tom would throw monthly get-togethers at the club where we bonded over pizza, beer and soda. Thus, the Mountainside Fitness family was born.Tom founded Mountainside Fitness on community, and this continues to be at our core as we grow into 20 locations and over 100,000 Members this year. As the leading fitness destination in Phoenix, we strive to provide our Members value with offer 80 high-quality group fitness classes included in membership, engaging childcare you can trust, state-of-the-art equipment, clean facilities, and of course, towel service.
