our classes/age groups


Our classes consist of warmups, conditioning, drills, technique, and live rolling/sparring. We pride ourselves on delivering tough, rigorous training, and continuing the regiment that Carlson Gracie envisioned.

Ruffhouse Jiu Jitsu is great for self defense, getting in shape, and most importantly challenging yourself. Only the strong survive, and if you aren’t tough enough, we will make you!
