Coach William Miller
Kru William Miller began his Muay Thai career at 16 years old in Grand Rapids, Michigan. What began as an outlet for teenage angst soon grew into a lifelong love the sport, fitness, and martial arts in general.
Kru William has trained in boxing, kickboxing, and Muay Thai in a variety of gyms – including Thailand, resulting in his unique fighting style that still stays true to the sport and culture. He received the title of “Kru” in 2025 under Kru Rex Terpstra and Ajarn Kevin Seaman, becoming a certified WTBA instructor and further solidifying his involvement as a coach. His pursuit of knowledge and experience has even led him to a certification in Thai massage!
New to the Denver area in 2025, Kru William is excited to join the Apex team and spread his knowledge and passion for the sport to others. His commitment to promoting a positive, safe, and fun training environment, detailed instruction, and personal growth both on and off the mats are sure to help you reach your goals!
