Coach Corey, along with his business partner Coach JT, started Catalyst Sports back in 2014 with the goal of helping up and coming baseball players reach their potential. As their business and passion for the sport grew they expanded into fitness and exercise training for youth athletes along with the general population. Thus, Catalyst Fitness was born.

Coach Corey is not only going to help you get in phenomenal shape but will make you a better athlete while doing it. Many of the exercises and training equipment he uses can’t be found anywhere else in the state.
