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.”

What Castle Rock Members Say

90+ Google reviews · Easton Castle Rock

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.
