About Carl

Coach. Competitor.
Referee.

Second-degree Brazilian Jiu-Jitsu black belt and gym owner based in Montreal.

I teach Jiu-Jitsu as a system of positions, reactions, and choices—not a collection of isolated moves.

I want you to recognize the position, understand the opponent's reaction, and choose an answer you can test under resistance.

The same principle shapes my rules work. Competition knowledge should change how you move and decide—not live as trivia you remember after the match.
