Crossover Brazilian Jiu Jitsu Academy

“Crossover BJJ is like a family! Over a decade ago, my kids started attending youth classes here. Professor Bob and the coaching team are absolutely fantastic with the kids. They not only focus on technique and skill but also instill important values. They educate the children on when, why, and how to use jiu-jitsu, all while keeping the sessions enjoyable. Now, after a decade, both of my boys proudly continue their journey as blue belts. The adult classes boast a wonderful community of people. Having been part of Crossover for more than 10 years, we've seen many faces come and go, but a dedicated core group remains committed to honing their skills and sharing their knowledge. For beginners, this gym is an excellent choice. The fundamentals class covers essential basics, perfect for those uncertain about grappling or "rolling" with others. From youngsters to those young at heart, Crossover caters to all ages. And let's not forget Yoga on Monday nights with Inga—it's not your typical yoga class; it's way better!”

“We've had our daughter training Jiu Jitsu here for almost a year now and we love it. The instructors are great. I really appreciate that they stress a positive, non-violent philosophy and that they try to build character. Benefits for my child also include confidence, developing a love of exercise, a lot of fun, and of course developing good self-defense skills. I highly recommend the academy.”

“I'm willing to travel 1.5 hours to come train down here with these guys, that should tell you everything you need to know about how great this gym is! Top notch coaching with Professor Ryan Courtney and Bob Duffey. The facilities are great as well. Get instruction and facilities aside, it really feels like you are apart of a big family once you join. You won't find a more welcoming group of people to train with!”

“Bob and Ryan are awesome coaches with a high level of BJJ skill as well as awesome instructors that will help you learn fast! If you are in the Wauwatosa or Brookfield area, definitely check out training with them at Crossover.”

“I've been to this gym for some specialized training to help me be a better police officer. The owner has expert-level knowledge and is willing to share that knowledge to make better cops. I have also attended other training events where Bob has used his knowledge in BJJ to show how it crosses over to solid concepts that help cops control resistive people from levels of simple resistance to life threatening resistance. Thanks Bob!”
