Samantha Radysh
"Coach Brian and his staff are great. Very patient with my shy 4 and 5 year old boys but still good at enforcing rules and helping them get outside do their comfort zones!"
Harley Mehlhorn
"Extremely welcoming gym with dedicated staff. Truly captures the spirit of Jiu Jitsu. The culture of the gym is second none and everybody from the instructors to the fellow lower belts are helpful, kind, welcoming, and knowledgeable. I highly recommend this gym for anybody looking to get into or continue their Jiu Jitsu journey."
Kelly Geister Schwarz
"This place is uncreditably welcoming and compressive. I was amazed with how the first coach(Josh) we worked with was able to meet the needs of our entire family and where we are all at with our ability. Everything was transparent and motivational, but they will make you work for it, in the best way. I also appreciated Josh's ability to accommodate some of your family's learning disabilities and was able to explain the movements in more detail, one on one, to ensure fair compressive support"
Daniel Ayd
"I dropped in here on a Friday afternoon for an open gym in my quest to grapple in all fifty states. As a visitor from just across the border I was greeted with open arms by Brian and a handful of folks taking a break from work so I won't tag anyone by name! Super clean gym with great high ceilings, lots of windows, and the ability to let in fresh air with garage doors that even had screens is a nice touch. The Fuji mats are fantastic and seem brand new which is great to see owners offering top quality gear for their students. Anyway, great gym and great people and it's awesome to see a law enforcement centric gym because they really should be training grappling arts --it's a matter of survival!"
