I’m an older grappler from out of town and dropped in for a 6am bjj nogi class. Coach Lee was excellent and took time for corrections. Great sparring with others. Recommended.
I had heard good things about this place through the grapevine and that it was a friendly environment for all walks of life but it turns out that was not true. We went in the morning hours because were interested to see what daytime fitness classes were available for us to observe and also possibly inquire about personal training for seniors but the girl at the desk didn't even look up at her phone from us for about two minutes and finally when she did she said "I'm sorry but I don't think that this is the place for you." assuming because my husband and I are older. Needless to say we were appalled by this treatment and will be looking elsewhere for fitness advice and guidance.
The best gym in town for getting into martial arts, great weight room. Staff makes you feel welcomed. They love what they do and love to see everyone improve.
I am glad found this gym and I love it. I wanted to find a BJJ gym but a friend had invited me to a Muay Thai class so I tagged along. And I have to say the rain I joined was John Bassford the instructor. He really seemed to know what he was teaching, very knowledgeable, and technical. I didn’t realize how knowledgeable he was until my recent trip to Thailand to train at Bangtao Muay Thai. They have many pro fighters coming out of this gym. And I feel like John’s program is very on par with the training in Bangtao. Our group of 15 seemed to perform very well in the Bangtao Muay Thai classes. Very happy John showed us the clinch and the importance of it. Of course I also picked up BJJ. The reason I was looking for a gym in the first place and the instructors are great as well. Stephen and David have really been great to me in helping me compete in local tournaments. I’ve done 5 so far and have gotten nothing but a ton of support here.
Couldn’t have had a better experience. Walked into Undisputed with an interest in BJJ and Brandon and Cassie gave me a tour and signed me up for a trial class later that week. I joined immediately after. I’ve now trained at several gyms since moving away and can confidently say this gym is top tier when it comes to their coaches, friendliness, and safety. They take time to get to know their students and are welcoming of all skill levels. Their women’s BJJ program is especially fantastic and I have yet to find anything like it. The gym environment is fun and laid back, but takes training seriously. It’s such an approachable environment for beginners and helped me stay consistent in my training. The opportunity to train with several brown black belts was an invaluable experience. David, Stephen, Yvonne, Tara, Ginny, Gerald, Natalie, Brandon, Cassie, and John were life changing connections and teachers! Thanks for everything, y’all!
