Andrew Kooner - Coach

Andrew Kooner

Andrew Kooner began boxing at the age of 13 in Windsor, Ontario. An Olympic and Commonwealth Games athlete, he has competed in numerous international competitions. In the 2000 Summer Olympics, he lost in the 2nd round in the flyweight division. At the Commonwealth Games, he won the bronze medal in 1998 and the silver medal in 2002. At the 2004 Summer Olympics, he tied for fifth in the bantamweight division. While still competing as an amateur, he also defeated Juan Manuel López.

Andrew is a strong advocate for health and exercise for all populations and is committed to sharing his skills and experience with Rock Steady boxers. The opportunity for people with Parkinson’s to be coached by an Olympic boxer increases the motivation and enthusiasm of participants for Rock Steady Boxing Toronto classes and their many benefits.
