Training with Coach Jack has been an incredible experience! His ability to explain techniques clearly and tailor his coaching to my skill level has helped me improve so much. He’s supportive, motivating, and always pushes me to do my best. Every session is challenging, but I leave feeling stronger and more confident. If you’re serious about Muay Thai, I can’t recommend Jack enough!

I’ve been training with Jack for a few months, and I can honestly say it’s been an incredible experience. Each session is not only fun but also packed with useful, hands-on knowledge. Whether you're a beginner or more advanced, Jack tailors each class to meet your needs, always ensuring you’re learning something new. His expertise in Muay Thai is evident in every technique he teaches, and he’s a fantastic communicator. He breaks things down in a way that makes even the most complex movements feel accessible. Beyond just the technical side, his passion for the sport is contagious, and it keeps me motivated to push myself every class. Every class leaves me feeling stronger, more confident, and excited to continue learning. If you’re looking for a trainer who combines expertise, patience, and a genuine love for Muay Thai, I highly recommend Jack.

My son, Roman, and I have trained with Jack for almost 2 years. In that time Jack coached Roman from an absolute beginner to his first points muay thai match. Jack not only taught Roman muay thai, but planned his strength training, conditioning, diet and worked with him on fight strategy and mental preparation. The result was that Roman was able to beat an opponent with four times more experience. More importantly Roman came out of the experience more fit, healthy, and confident. The experience was so positive that Jack is now training one of my daughters. I can't recommend Jack highly enough.

Hi all - I have been training different martial arts for 7+ years. And, Jack is by far the best coach I've ever had. For starters, Jack is incredibly passionate about coaching - that's what he wants to dedicate his life to. This shows in the passion with which he approaches coaching sessions as he studies, prepares for sessions, and comes to each session with an individually-tailored plan that allows you to progress towards your objectives very rapidly. Jack's approach to fitness is also unique because of his competitive Muay Thai background. He not only focuses on aesthetics but also on holistic fitness that could serve an advanced martial arts practitioner in any situation. Lastly (and probably most importantly), most of the value that you get from training with Jack comes from his desire to coach the mind as well as the body. He really cares for you during the training sessions and uses Muay Thai and Fitness as tools to help you develop your mind in a healthy way - he's a great listener and legitimately cares about your well-being, confidence, health, and happiness. If you're thinking of working with any trainer in the Bay Area, don't hesitate: choose Jack. And, if you're still dubious, feel free to reach out to me. I'm happy to provide a reference via the phone. Andres
