"I've been taking the Muay Thai classes with coach Dave Sullivan for the better part of two and a half years. Coach Dave is the type of coach who will not just work on strengthening your weaknesses, but also refining your strengths. As someone who has been a boxing/combat sports hobbyist about for 21 years, I consider his class to be one of the best authentic learning experiences I've had! Would definitely recommend anyone from beginner to advanced levels to check him out!"
"Been training Muay Thai with coach Dave at Mau Mau’s for almost two years now. He has great knowledge of Muay Thai and makes every student feel welcomed, regardless of experience. The class is getting bigger over the past two years (more sparring partners :D !!) and I’ve seen many new students join the Muay Thai class and remain consistent. Not only is Coach Dave a great practitioner, he is also excellent at conveying his knowledge. I’ve improved a lot since training with him, and I hope to continue to do so."
"Mau Maus jiu jitsu academy has a great environment for students of all levels. Ive been there almost 6 or 7 years and I love it. More recently I signed up with Kru Dave for Muy thai and absolutely love it as well. I've been training with Dave for almost a month and already feel major improvements in my striking. He focuses on very technical details and his class is even more informative. Great vibes and all his students are very welcoming and patient with newcomers. I would highly reccomend checking out a some classes if you are interested in learning real and authentic muy thai!!🙏🙏🙏"
"I have been training at Mau Mau’s on and off for a few years, and it is always a great place to come back to. The BJJ program is welcoming and well-run. Same with the Muay Thai program under Kru Dave. Overall, solid place to train and grow, no matter your level."
