What Our Students Say
Hear from our community about how training at our academy has impacted their lives.
Emily Wooten
"I dropped in here about 2 weeks ago when I was in town for a business trip. Very welcoming environment. Plus, they have several other ladies, which is always a great find in a gym! Thank you for your hospitality!"
Youn Chang
"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."
Ahlam Javed
"If I could give zero stars I would. Very unprofessional gym. Set up a class with the main instructor/owner Brenton, with a large group of kids, confirmed with him a few days before and he never showed up. The gym was closed, wouldn’t answer his phone either. It was very upsetting to all the kids and families who drove out for this class that was planned well in advance."
Patrick Johnson
"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"
