Panyapol (Bruce) Ratanakul-Owner, Managing Director, and Head Coach
Chonburi Muay Thai (CMT) was founded by Panyapol (Bruce) Ratanakul. Bruce was born in Thailand, where he began training in the art of Muay Thai at the age of 10. Over the years, Bruce has won 16 of the 21 Thai fights in which he competed. He has trained under both Ajarn Petchpayao (2-time Thailand coach of the year) and Kongnapa Watcharawit (Rajadamnern champ at four different weight classes). Bruce received additional combat training as a proud member of the U.S. Army and returned to his true passion after being discharged, teaching and being an ambassador of Muay Thai in the United States.
Bruce continues his mission of expanding this art in America by coaching beginners to advanced students, amateur and professional fighters in promotions that include the UFC, Bellator and One Championship. To date, Bruce has coached over 300 fights, bringing traditional Muay Thai to countless communities. Bruce maintains an active role at the gym and he can still be found teaching beginners class and mentoring the next generation in our Youth Muay Thai program.
David Khamhuang-General Manager (2x Tennessee IKF Cruiser-WT Champion)
David has been training under head coach Bruce Panyapol for 10 years. His ongoing training and pursuit for more comes from his competitive nature, which he strives to inspire in others. When he is not in the gym, David is coding for web development, pursuing personal projects, or cooking up meals to complement his TV binge watching. In quieter moments, David enjoys reading books such as 'Fahrenheit 451', 'The Plateau Effect', 'The Tipping Point' and 'Woman in the Window'.
Chiké Obianyo (13-7, 3x Tennessee IKF Light Middleweight Champion)
Chiké has trained under Bruce for several years and was the first person whom Kru Bruce trusted to be a CMT coach. He has competed in many fights, within various promotions and had considerable success. Chiké can be found at CMT teaching weekly classes to include beginner, all levels, and clinch while also conducting private lessons. Chiké grew up playing both soccer and football and remains a sports fan. He also enjoys seemingly paradoxical pursuits such as learning about new technology while also studying philosophy. Chiké believes that there are many paths to success and that anyone has the ability to achieve.

Jason Campbell (9-1, Cruiser-WT National Tournament Champion)
Over the past 3 years, Jason has been training at Chonburi Muay Thai. He works hard and he is a stoic, fierce fighter. Jason endorses the positive influence that Muay Thai has had on his life, reinforcing self-discipline and providing him with tools to effectively face adversities. Jason has seized the opportunity to pay forward what he has received and oversees the bag classes. He has an encouraging style and students know that he would not ask from them anything that he was not willing, himself, to do. When Jason is not coaching or training, he continues to grow his modeling career.
(D.C.) Damontez Cox
D.C. moved from San Francisco to Nashville in 2020 after earning a Law degree from Golden Gate University. His first Muay Thai coach recognized DC’s potential and encouraged him to continue training, leading him eventually to CMT. D.C. is a positive and playful being with a palpable energy that is familiar and welcome. DC has the same expectation for others that he holds for himself: to achieve to their fullest potential. He says simply, “If you never fail, you’ll never know what success feels like.”
Hannah Booth (4-0, Straw-WT National Tournament Champion)
During a transition in her life, Hannah began her Muay Thai journey. Hannah found comfort being in an environment that is simultaneously accepting and challenging. After training for 3+ years, Hannah began working at the front desk. During this time, she modeled and maintained the inclusivity of the gym environment, making members feel welcome and seen. Hannah continued training and growing and last summer she won the 2022 TBA-SA Muay Thai Tournament Classic Championship. With a renewed confidence and desire to always push herself toward a new challenge, Hannah began teaching classes. She currently shares her love of Muay Thai by coaching youth classes and conducting private lessons.

Martial arts is one of his main passions in life, when he and his wife moved to Nashville in 2020 he had the fortune of finding Chonburi Muay Thai. After his first class, he was hooked and could feel the amazing, supportive, and safe environment that Chonburi had established in their gym.

Zach has a natural gift for teaching kids and can connect with them in a way that can help any new student walking through the doors feel confident, comfortable, and safe.
