Harley Casto









My name is Harley Casto and I’ve been training Jiu Jitsu for almost three years now. I started training because it was fun and challenging. For me, Jiu Jitsu is more than a sport and a martial art; It’s a way of life. The Jiu-Jitsu way of life is best described as a life-style of respect. Respecting yourself and all others around you. I train Jiu Jitsu to stay healthy and to compete in tournaments. If you are interested in Jiu-Jitsu then you should come down to 10th Planet Springfield and train with Mike and I.
