Present in over 48 locations across Quebec, as well as in several schools (extracurricular activities), Groupe Karaté Sportif distinguishes itself through its teaching method focused on positive reinforcement and motivation. The classes they offer don’t just aim to master karate technique, but they also cultivate respect, perseverance, and self-esteem. For over 35 years, the Karate Sport Group (GKS) has been helping thousands of children develop their confidence, focus, and discipline through a unique approach that places children’s education and personal growth at the heart of every class. “For us, karate is a pretext for teaching life,” explains Marcelin Cantin, president and co-founder of Groupe Karaté Sportif. We spoke with Cantin to learn more.
