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 including, Amin Almelik, Elijah Halliday, Ferdaws Nayimi 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.



Coach Mel has been training in Muay Thai & Kickboxing for over 5 years under Kru Chris. What started as a pursuit to achieve her fitness goals, quickly grew into a desire to learn and further develop her skills. 

Mel began instructing and has since received her Poo Choi Kru (Assistant Instructor) certification in 2018 from Ajahn Suchart and the Sports Authority of Thailand. 


Mel embarked as a student of martial arts at the age of 35 and believes it’s never too late to acquire new talents and ignite unknown passions. Her dedication and commitment to learning, and the guidance she provides to the students has made her a valued member of the Markham Martial Arts team.


Kru Philip Chong was born and raised in Hong Kong with his parents and younger brother. He vividly recalls how his pursuit of Muay Thai began as a young 17 year old, strolling through the streets of Hong Kong where he stumbled across a Muay Thai gym. His curiosity led him inside where he watched the students train. He was amazed how brutally beautiful the striking techniques and exchanges were, and wanted to experience it himself. None of his friends were interested in joining, as Muay Thai wasn't popular during that time, so Philip enrolled on his own.  After a few months of rigorous training, he started to compete and hasn't looked back since. Philip has had the opportunity to fight at different levels against fighters from his native Hong Kong as well as Thailand, China and most recently Canada.


What Philip didn't anticipate was all the amazing things Muay Thai would do for his personal development. It helped build his confidence and taught him to manage his emotions when dealing with difficult situations. His training challenged him both physically and mentally and shaped him into a strong, resilient person.


In 2020, Philip embarked on another big life challenge and moved to Canada with his wife and son. He arrived during a very difficult time as the first wave of Covid lockdowns were enforced, making him unable to work or train. It wasn't until he met Kru Chris Williams at Markham Martial Arts, who gave him the opportunity to live his dream and rebuild his career as a professional Muay Thai Fighter and Coach. Since joining the Markham Martial Arts team, Kru Phillip continues to strive for his best and is ready to fight his way into the Canadian Muay Thai scene.
