Crossover Brazilian Jiu Jitsu Academy

Crossover Brazilian Jiu Jitsu Academy is led by Professor Ryan Courtney, a 3rd-degree black belt who earned his rank under BJJ Master Rigan Machado and Coach Marc Laimon. Ryan brings a competitive background that includes MMA and numerous grappling tournament victories, alongside extensive teaching experience with organizations ranging from local schools to the United States Army. The academy’s instructor team also includes seasoned black belts like Professor Bob Duffey, a certified defensive tactics instructor with over 20 years in martial arts and law enforcement training, and Professor Dan Boxley, a Rio de Janeiro native with a decade of BJJ experience and Muay Thai training under Duan “Bang” Ludwig. Classes at Crossover BJJ cover a full spectrum of Brazilian Jiu-Jitsu, from introductory fundamentals to intermediate and advanced techniques, with a curriculum that balances sport competition skills and practical self-defense. The academy offers gi and no-gi sessions, including specialized classes on leg locks and open mat times for adults. Kids’ programs serve children starting at age five, with separate groups for younger and older kids, taught by instructors like Professor Bob and Coach Erik. Women’s only classes are also available, led by Coach Jaimie Boparai and Coach Sarah Rens, both experienced practitioners with long-term involvement in martial arts. Beyond BJJ, Crossover integrates striking arts through kickboxing classes and supports flexibility and mental focus with yoga instruction from Coach Inga Bentley. The academy operates at its Wauwatosa location with wheelchair-accessible facilities and welcomes drop-ins. Its approach emphasizes realistic skills, competition readiness, and fitness, all taught by a diverse coaching staff with deep roots in both Brazilian Jiu-Jitsu and related disciplines.
