Train Brazilian Jiu Jitsu at Easton Castle Rock

Our Castle Rock Brazilian Jiu Jitsu program runs from true-beginner fundamentals to advanced and competition training. No experience needed to start — most people walk in having never grappled, and experienced grapplers get a room full of training partners to push them.

Derek McCracken had a black belt in Tae Kwon Do and 23 years in it before he ever looked at jiu jitsu — and he only looked because he wanted to teach his own students a few basics. He took one class at Castle Rock and never went back. He runs the program here now, a brown belt promoted by Derek Alumbaugh, with medals at every belt from white through brown. “How you do anything is how you do everything.”

I have been coming to Easton just under a month now and have loved every second! I tried bjj about 5 years ago and stopped due to a combination of things which left me feeling really intimidated to try bjj again. Erin got me to sign up for the free class and I had so much fun, though. Coach Kevin and Coach Ray, as well as everyone else at the gym, are extremely helpful, patient, welcoming, and kind. I am extremely out of shape and haven’t been made to feel bad about it at all. I love that there are a decent amount of women who train here too. Really excited to keep learning and growing at Easton!

I have been going to Easton for roughly a year now. Everything about the school has been fantastic. The students, instructors, mat space, etc. The atmosphere is focused around all the students, not just a small group of the high achieving students. For background I started training bjj 20 years ago.
