CASEY KAMMEL
Casey earned his B.S. in Exercise Science from California State University, Long Beach, after successful high school and college baseball careers. While studying kinesiology, he became an ACE certified personal trainer in 1992 because he liked fitness and then became a competitive bodybuilder.
In 1994, Casey suffered a life-altering injury after he dove into a swimming pool. He broke his neck by fracturing the C4 vertebrae, becoming immediately paralyzed from the neck down. (Read more in Casey’s Story above.) While Casey was still confined to a wheelchair, his clients begged to train with him and glean the motivation they desired to meet their fitness goals. Casey fed off their energy and thru perseverance and intense exercise, he learned to walk again. And now, he is a competitive physically-challenged triathlete. He has completed many since his first sprint in 1999 and even attempted the Kona Ironman World Championships in 2014. Just 8 miles shy of the marathon finish, Casey was pulled from the race due to medical complications.
Casey is a true testament to leading a healthy, active lifestyle and never giving up. His motto? “Failure is not an option.”
LISA KAMMEL
As a former soccer and volleyball player, Lisa became an ACE certified personal trainer in 1992 because she wanted to learn about weight training and staying fit. Anatomy and physiology classes at California State University, Fullerton spurred her interest even more.
She earned her B.A. in Public Relations and immediately began working for ASICS America, leading sporting goods manufacturer, and continued to train clients on evenings and weekends. In 1997, Lisa, along with Casey, opened Executive Fitness, a business dedicated to customer service through personal training, group classes, corporate wellness, and more.
Lisa says she works out daily because she loves lifting heavy weights, wants to stay fit, and to defy the aging process! As a mother of two, Lisa declares “family first” and takes great pride in watching her girls’ athletic endeavors.
What resounds in her head? “Be present".
