Membership & access info →Tim is an exceptional coach with a genuine passion for both martial arts and teaching. What really sets him apart is his ability to explain techniques in a structured, clear, and accessible way to students of every level. He builds a strong foundation first and then gradually adds more advanced concepts — my progress has been significantly accelerated because of his coaching.
Cas VeningaMy Jiu-Jitsu and grappling have improved extremely rapidly, and the single biggest factor has been Tim's coaching. He doesn't just teach random, unrelated techniques — he has a game plan built on systems and concept-based Jiu-Jitsu that builds strong fundamentals. His range across judo, wrestling, jiu-jitsu and striking turns you into a well-rounded grappler.
Luke ReichelWhat I like most is that it never feels like you're just another client. His advice is never generic — he takes the time to understand you, your style, your strengths and weaknesses, and gives advice that actually fits your situation. If something doesn't click, he'll explain it from a different angle until it makes sense.
Alex MoreauStarted training here with no previous experience and have learned an incredible amount in a short time. Tim is patient, knowledgeable, and genuinely invested in helping everyone improve. His way of explaining things is on another level.

Competing is optional — most students never do. For those who want it, there's a path.
I teach these sessions as part of each venue's own class schedule — access, pricing, and booking go through them directly, not through Barracuda.
