Since 2012
About Us
Our classes focus on teaching proper technique to all of our students, regardless of skill level. We welcome you to join us regardless of your experience or training goals.
Our Gym
United Thai Boxing & MMA was established after the Triangle’s only Muay Thai-based training gym closed suddenly in 2012. We realized that no other gym in the Triangle area offered authentic Muay Thai-based training with the same frequency and quality. United Thai Boxing & MMA was created to fill this void for everyone from novices looking for a great kickboxing workout to professional Muay Thai and MMA fighters. We chose the name “United Thai Boxing & MMA” because our members are United by a love for Muay Thai, mixed martial arts and the desire to help each other improve through hard work.
Technique-Focused Instruction
Our Instructors
William "W.W. II" Wilson - Head Boxing Instructor / Pro Boxer
As a professional fighter, William “W.W. II” Wilson is a quick and calculated fighter who reads his opponents, setting the pace of his fights. A fighter fans love to watch, he has fought several live bouts on television. He’s a real contender and well known in the NC boxing community. With 16 pro fights under his belt, W.W. II has proven time and again that he has what it takes to hold his own and be a champion. “Some boxers have never had a loss. I learn from everything I do, win or lose. If I lose a fight, I have actually won if I learned from my mistakes and used the experience to become a better boxer.”
William also shares his knowledge as a trainer. Coach William has a natural skill to pull out the best in everyone! He leads by example. Coach trains hard before his class and then holds his students up to the same standard of hard work, dedication, conditioning, drills and use of good technique. And if you are lucky, he sends you home with homework assignments to make yourself a better person and boxer. Every class he encourages you to demand more from yourself.
