I am a Firm Believer in Strength through Technique. With my experience in Boxing, Kickboxing, BJJ, And MMA I've found that style points don't hurt either. I have been competing in Combat Sports for 9 plus years, and in that time I have won 3 amateur Belts and one Pro Title Belt in MMA. I was awarded my purple belt( and still learning/expanding my knowledge) in BJJ, and would have gotten nowhere had I not put my time in on the mats. With my classes I take a hands on approach in teaching and coaching both my teammates and students, as well as, expanding and innovating mt personal approach to Martial Arts.
