History of Sonora Fitness

In the Beginning

Sonora Sports and Fitness Center opened for business April 1, 1992. Our original facility was 13,000 square feet. We offered weight training, 14 aerobic classes per week, two racquetball courts, an assortment of cardio equipment such as lifecycles and Stairmaster climbers, and our childcare hours were from 9AM-1PM and 4-8PM, Mon-Fri. We had a total of 17 employees.

During the past 15 years we have reinvested over 4 million dollars for new equipment and facilities and have grown to 50 employees, 2 pools, 4 racquetball courts, two separate workout facilities, over 32 exercise classes per week, and much more. This quest to improve our facilities parallels our desire to be part of and positively impact this community. We have a philosophical aspiration to spread exercise and its benefits throughout the county.

First Improvements

September 16, 1992, less than 5 months after opening, we completed construction of a 75 foot by 40-foot swimming pool. At the time of completion we were the only facility to offer a heated pool year-round for lap swimming and aquatics programs in the county.

Constant Growth

Three years later in November of 1995 we completed a 1,500-foot expansion of our exercise floor, adding 10 new treadmills and 5 Stairmaster 1650 cardio/strength machines.

November of 1996 we completed our next 10,000 square foot expansion. The new facilities included a brand new group exercise room, two additional racquetball courts, and an expanded Physical Therapy office leased by Sonora Regional Medical Center.

July of 1999 we opened a 5,000 square foot childcare/martial arts facility. This new building allowed us to expand our childcare hours and freed up additional space for an infant specific room within childcare. We were fortunate to secure Tripps Tae Kwon Do as a tenant.

In September of 2008 Zoo-phonics/Safari learning school opened and took over the child care for our members and staff.  This company has over 30 years experience in the education of young children. We are so proud to be a part of this offering.


In April 2003, just 11 years after opening, we completed our largest project to date, adding a new building and a pool encompassing 25,000 feet as well as 30,000 feet of off-site improvements such as secondary access and expanded parking. These facilities allow us to provide programs specifically for the youth of Tuolumne County. We built an expanded multi-purpose gymnasium for basketball, volleyball and a host of other indoor activities. Our prized addition from this time is a competition-grade swimming pool. The pool has 10 lanes, which is more than double the size of our pool built in 1992. The Tuolumne County Aquatics youth swim team practices here and our Masters program has grown to the 3rd largest in the country since the addition of our beautiful pool. We are able to offer adults a choice of 31 workouts each week as well as introductory swimming classes and private lessons to adults and children. This addition of a second pool also allows us to provide the necessary access and temperature for our aquatic classes in our adult center pool.

In October 2007 we completed another renovation and upgrade. We purchased new cardio and weight machines, and re-carpeted and painted the adult center and upgraded both the men’s and women’s locker rooms.   

Our Commitment and Mission

These continual improvements and expansions are always embarked upon with the desire to provide superior facilities and quality fitness programs to meet the needs of the youth and adults in Tuolumne County. As our mission statement proclaims, it is our desire to provide an educational, nurturing, safe, and healthy environment for our members.
