Grappling Mastery’s BJJ, and Muay Thai classes have taught me so much. is a great instructor and I would highly recommend his classes. I initially joined to learn self defense, and after a few months feel able to defend myself in any situation. I enjoyed Brian’s classes and instruction so much that my interest has gone beyond self defense and progressed into a passion for Brazilian Jiu Jitsu.
