I took my first ever MMA class here in 2016, while I was in college. I've lived in many states and have been to many gyms. To this day, it's the best gym I have ever been to. The foundation that they instill in you will carry you for the rest of you MMA journey. I wish I still lived in CT to go to this gym. Truly the best is the business!!

I recently brought my 7 and 4 year old to begin training in BJJ. To my delight they loved it even more than I expected. Marissa and the other trainers are wonderful with the kids, making it the perfect combination of fun and discipline. I don’t know which is better, how accomplished my boys feel every time we leave or how they ask me every day when they go back to MMA. Highly recommend for any parent looking for a healthy and productive outlet for your child.

Ultimate MMA and their exceptional instructors, Andrew and Marissa, provide an outstanding experience. Whether you're young or old, their top-notch Jiu-Jitsu classes cater to all. Personally favoring the Gi classes, I can attest that this gym is perfect for anyone new to martial arts. The atmosphere is humble, and everyone, (just like they did for me from day one) is ready to lend a helping hand. Expect improvement and a boost in self-confidence. A solid 5 out of 5 recommendation!

This is an amazing facility. It is extremely clean, friendly, fun, even humorous at times. I love the energy. The team spirit is epic. This organization will get you in tip top shape, teach you unparalleled discipline and self defense unknown. Andrew and his team are true leaders in this defensive sports arena. I’ve been to many facilities over twenty seven years. This place is great. Especially for children. Its so safe and friendly. For adults, well we’ll just let Andrew’s pattern history of professionalism and commitment to combat sports speak for this group alone. His MMA training form and technique both defensively and offensively are unrivaled and unparalleled in our territory. I highly recommend this facility. Give it a hard go. You will love it. Your kids to. This is the place to be. Lets go harder!
