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.
