About

Ready to learn how to defend yourself?

Whether your goal is to lose weight, gain muscle, boost your fitness or become healthier—I’ll help get you there.

Now sitting at 6'5" and 225 lbs, I’ve been the skinniest guy in the room, the chunky guy and the least equipped to defend himself at different times in my life.

At 34 years old I now have a 10-0 fight record, over 10 years of experience in Muay Thai, Strength & Conditioning Training and Fitness. I design tailor-made plans for each individual geared towards multiple goals:

- Traditional Muay Thai, Boxing and Self-Defense

- Weightloss

- Muscle Gain

- Strength and Fitness

NOW OFFERING WEEKLY CLASSES – ASK FOR DETAILS

Whether you’re just starting out or looking to level up, our Muay Thai classes are designed to be accessible for all budgets. We believe everyone should have the chance to train, grow, and feel confident—without breaking the bank.

Private group sessions are also available, and I offer customized Muay Thai camps for companies, schools, or teams.

As your coach, I’ll guide you through every step—building your ideal body, improving your fighting ability, and boosting your confidence. We focus on one habit at a time so progress feels natural and lasting.
