I have been training in mixed martial arts for over a decade now, and visited Mat Chess today for the first time. It offers excellent Brazilian Jiujitsu and wrestling instruction, with high percentage techniques taught with attention to detail. The instructors are skilled, friendly, and helpful. Also, their kick boxers were some of the best I've seen in the state thus far.

I try to visit Mat Chess when ever I'm in Seattle . They have great programs for BJJ, wrestling and Muay Thai. Andrew is a great instructor and I always pick up some valuable knowledge during his classes. What I really like about Mat Chess is the laid back, friendly environment. If I lived in Seattle, it would definitely be my second home. Thanks for the great training guys.

Great gym with a great staff. Andrew runs a tight ship at Mat Chess. Very supportive and involved coaching staff there. They have a great BJJ program and an amazing Muay Thai program as well. The atmosphere is very humble and focused. No major ego's in this gym. Everyone knows their place and it makes the learning experience that much more fruitful. All the coaches have a deep and very technical understanding of their craft and make no reservations on dispensing knowledge. Mat Chess is doing big things. Keep it up!
