He won his first kickboxing competition in 1976 after only six months of training under the direction of John Therien, and subsequently became Canadian Middleweight Kickboxing Champion two and a half years later.

In 1980, he won the title of the World Middleweight Kickboxing Champion, and held the championship for a record 15 years.
He was referred to as “The Iceman”, a nickname given to him by Rodney Batiste due to his intimidating icy stare and cool demeanor in the ring.

Today, Jean-Yves has also become a world-class promoter for the sport of kickboxing. He is a true ambassador for the sport, giving back so other ambitious athletes can realize their dreams.
