First time doing any martial arts and I love it. Great gym, everyone is friendly, and you’re learning from a true professional who’s also a great inspiration.
I dropped in for a beginner Brazilian Jiu-Jitsu class last month, and it was a great introduction. The facility is spacious with large matted areas that feel clean and well-maintained, plus plenty of bags and equipment around. The instructor was patient and detailed, making sure everyone understood the techniques without pushing too hard. Everyone on the mat was respectful and helpful, creating a supportive vibe even for newcomers. Parking is easy right on Concession Street, and the location up on the mountain is straightforward to reach. Solid place to train consistently.
Amazing place to train! I started here pretty recently and have found that Jeff is a wonderful coach, and the other practitioners are stand-up individuals without exception. Great space, well maintained equipment, and an ethos to match. I'm finding that by coming here I am starting to feel safer and better able to protect myself, my coworkers, and the people whom I serve. Thank you Jeff. Sincerely, thank you.
I came in to train here when I was working a short term contract in the area. Right away I was amazed at all the cool hand-painted murals there are outside and inside the gym. Everyone here was so kind and welcoming, I felt right at home here from the beginning. I learned some awesome techniques and then had some really fun rolls with the team afterwards. I will definitely make a point to come back here. It’s worth a couple hours of commuting to come to this incredible gym. The teaching here is second to none.
I started going to this gym 2 years ago with no experience. I was nervous but Jeff and everyone at the gym was very welcoming. This gym has a great community. Jeff has lots of knowledge to share, makes training fun, and teaches legit moves and tactics that real fighters use. The sparring at this gym is very good. No one trys to take your head off, and Jeff watches to make sure everyone is safe. I would highly recommend this gym.
