At Grizzly Gym, every member of our staff of instructors is both fully certified to teach, and additionally has significant in-ring experience.

Most of our instructors have held national championships; the head instructor has competed more than 250 times in over a dozen countries around the world. And the difference that level of experience makes in the instruction you receive is priceless.
