He has also won world titles in both the ISKA and PKC associations.  He became known as the “Iceman,” a nickname given to him by Rodney Batiste during his first title defence, due to his intimidating icy stare and cool demeanour in the ring.  Jean-Yves has a number of high-profile victories, including two wins against future four-time K-1 champion Ernesto Hoost and a draw against the legendary Don “The Dragon” Wilson.

He has also fought world champions such as Rob Kaman, Tosca Petridis and Rick Roufus.  Jean-Yves has worked with many groups and charities, such as Big Brothers and the Children’s Wish Foundation. He is the author of a book on kickboxing techniques and has a series of videos on the science of combat sports. He is the subject of a film produced by the National Film Board and was voted Athlete of the Decade by the Sports Writers Association of New Brunswick.  Since his retirement in 1995, Jean-Yves began teaching classes at various Therien Ju-Jitsu & Kickboxing schools and became a world-class promoter for the sport of kickboxing. He strives to give new, young fighters the opportunity to realize their dreams in the “Iceman Amateur Kickboxing Circuit”.  In 2011, Jean-Yves and his mentor Hanshi John Therien opened their own school, Therien Ottawa South.  John Therien has since retired, however Jean-Yves continues to manage and instruct at the school with his new partner Jason Lian.
