Business, Project Manager, Admin Support

Kelly completed her Bachelor’s Degree in Kinesiology, with a concentration of Exercise Leadership, and minored in Coaching at James Madison University in Harrisonburg, VA.

Stumbling into an unlikely corporate opportunity in management and sales, Kelly excelled and won multiple corporate awards for her achievements, with accelerated promotions in a fortune 200 company. Athletics experience played a dramatic advantage in this success - devising game plans, execution, scouting the competition, etc.

With personal medical needs such as multiple heart conditions, joint injuries, traumatic brain injury, PCOS, Endometriosis, Cervical Cancer, and Celiac Disease, Kelly fully understands the need for fitness and proper nutrition in medical battles. With previous success in management and sales, along with education and passion of fitness, Kelly found her home in working to grow these San Antonio, TX based businesses.

Kelly is a fitness guru, multiple time marathon runner, mom, dog mom, USMC wife of a Combat Veteran, vegetable and herb gardener, and loves to host and entertain friends. In any opportunity to talk fitness/nutrition motivation and education, Kelly jumps right on it!
