CATS History

Colorado Athletic Training School (CATS) was founded in 1988 by Rob Candelaria, a competitive gymnast at the University of Colorado and an avid rock climber.


Rob set out to build a gymnastics and rock climbing facility to involve more people in the two sports he loves. Rob built one of the first indoor climbing walls in the nation.


Later, he fell in love with a beautiful rock climber, triathlete, and gymnast, Wendy Rein and they married. Together, they run our programs! 


Among the reasons that our program is successful, is the dedicated coaches and staff who help our athletes realize their highest potential. CATS is host to athletes from recreational level to the highest competitive levels. 


CATS has been around over 35 years, and is still a favorite choice for gymnasts and rock climbers across the nation. CATS provides quality instruction, the best equipment available, and a community of healthy and active people! Come join our family!
