10th Planet Jiu Jitsu: Torrance

10th Planet Jiu Jitsu: Torrance is led by Sensei Marvin Castelle, a first-degree black belt under Eddie Bravo and founder of the Dark Arts Association. Marvin has dedicated over a decade to Brazilian Jiu-Jitsu, developing an approach focused on precise, submission-oriented no-gi grappling. His philosophy—“have a game plan and execute for the finish”—shapes both the advanced curriculum and the overall ethos of the academy. Alongside Marvin, the coaching team includes Coach Kirsten “Kay” Kuhar (brown belt), who heads beginner and kids programs, and Professor Mitch Milat (black belt), who brings a seasoned, fundamentals-driven perspective to early morning classes. The academy is rooted in the 10th Planet no-gi system, offering a full schedule of classes for adults and kids. Beginners are introduced through structured fundamentals classes, while advanced students can dive into specialized offerings like leg locks, rubber guard, and competition-focused pro sessions. Kids as young as three have dedicated classes designed to foster confidence and technical growth. For those interested in striking, the gym also provides kickboxing and boxing classes, giving students a chance to round out their self-defense and athletic skill set. Open mat sessions are a regular feature, with no mat fee and a stated “no politics” approach that welcomes visitors and encourages cross-training. Drop-ins are welcome, and the academy’s location and amenities—such as parking and wheelchair access—make it accessible for both locals and traveling grapplers. With a coaching staff committed to technical excellence and a clear identity in submission grappling, 10th Planet Torrance stands as a hub for no-gi jiu-jitsu in the South Bay.
