Owner & Head Instructor

Behind every champion is a trainer, and behind every trainer is the heart and soul of a champion. Christopher aka “Killa” aka “Professor Williams” was born on the small Caribbean island of Trinidad & Tobago. Growing up in Trinidad, he spent all his leisurely time playing sports. One of his favorite pastimes was watching historic boxing matches with his father.

The Williams family later relocated to the Bronx, New York. Following their move, Kru Chris’ father enrolled him in boxing classes at the local YMCA as a means of self-defense to protect himself living in a rough neighborhood, and to keep him out of the street lifestyle. Countless hours were spent at the YMCA trying to emulate his idols, Roberto Duran and Mike Tyson. It wasn’t until his move to Scarborough, Ontario where he was introduced and fell in love with Muay Thai. From that moment on, a passion was ignited and lifelong devotion to the sport began.


“I didn’t know why I loved it, but the ring became my second home. Muay Thai provided me with a feeling of serenity I never knew.”
- Kru Chris

Fast forward to the present day; Kru Chris has achieved many accolades in Muay Thai, most notably becoming a 4-time North American champion. He has lived and fought in Thailand, accumulated over 50+ fights in countries including Canada, United States, Mexico, and Panama. He established himself as one of the most notable fighters and coaches in the Canadian Muay Thai community. This was further solidified by being recognized in Canada as the “2016 Best Pro Fighter,” which coincidentally was the year of his retirement from his fighting career. While training to become one of North America’s prominent fighters, Kru Chris also pursued his interest in coaching becoming one of the youngest Muay Thai practitioners in Canada to receive the title of Kru (teacher). He has helped develop some of the best fighters in Ontario and many other WKA, TBA, IKF, WKF and MTO champions.


Kru Chris’ enthusiasm and dedication for teaching led him to pursue his dream of opening his own training facility, Markham Martial Arts. His goal and focus are to spread the love and passion he has for Muay Thai to all his students.
