Best gym around! Fluid is a superb group of people dedicated to helping each other learn and grow in the sport of jiu jitsu. I came in with zero grappling experience and was very intimidated to start—but the atmosphere and people made me feel very comfortable. Professor Brenton is a gem of a human being. So full of wisdom. He cares for his students’ safety and progress, and has a remarkable sense of humor (or at least he thinks he does 😋). I’ve moved out of state and cannot train at Fluid anymore unfortunately. If you’re in the area and looking for an open mat or gym to call home, I urge you to check out Fluid. BIG OSS to all my friends there ❤️

I began my Jiu Jitsu journey at Fluid about 3 1/2 years ago. I’m not super athletic, I’m not super strong and at the time I was 74 years old. At present I can say, this was the best thing I have ever done for myself. Fluid is a nurturing, friendly environment - at my age I have made friends decades younger than I and I continue to learn and grow in my Jiu Jitsu experience.

Fluid Jiu Jitsu is hands down the best gym in Milwaukee. Professor Brent and Coach Nick are both incredibly professional and respectful. Having trained in Jiu Jitsu for a few years before moving to the area, I checked out other gyms, but none of them matched the welcoming vibe of Fluid. From the moment I walked in, I felt genuinely cared for, which was a refreshing change from other places where I felt like I was just a target for intense rolling because I was new. The atmosphere at Fluid Jiu Jitsu is fantastic. Another great perk is the ample parking. You will never have to worry about finding a spot as there is plenty of parking for everyone.

When I walked into Fluid Jitsu, I felt something special right away. It was a warm and friendly place, totally different from my old gym where I often felt ignored. At Fluid Jitsu, they welcomed me warmly and saw my potential right away.The best thing about Fluid Jitsu is how good the instructors are. They really know their stuff and they care about helping each of us get better. They're not just teaching moves—they're helping us grow. Overall, Fluid Jitsu isn't just a gym; it's like a family. They make you feel valued and supported, and that's made all the difference for me after my disappointing experience at my old gym.

When I travel I always try to drop in and train at a new academy whenever I can. A year ago I visited Fluid Jiu Jitsu, and had an awesome time. Master Pedro Sauer was in town! Super kind, welcoming team! Great Jiu Jitsu! I found myself in Milwaukee again yesterday, and headed straight back for a lunch open mat. Warm welcome again and got a bunch of great rolls. This place is consistently great and that is important when choosing a place to train when on the road. I highly recommend. Thanks for leading such a great team, Professor Fitzgerald! See you all again soon I hope. #PedroSauerAssociation #Keepitplayful #FluidJiuJitsuMilwaukee
