Hammer Jiu Jitsu

“The best Jiu Jitsu gym for kids and adults in all Connecticut! Coach Wojciech and coach Adam are amazing. The way they welcome you and the vibes in the gym are always positive, all the students there are respectful and you can easily make new friends! The gym is always clean and this is something really important especially for a sport like jiu jitsu. If you leave in Connecticut in Fairfield, I recommend you to go for a trial class, you won’t regret it!”

“Absolutely love This place !!!! I thought my 4 year old was not going to enjoy it… and here we are 5 months in and she asks everyday if she has Jiujitsu. The Professor and all the Coaches are super amazing.”

“Great jiu jitsu gym with amazing staff and facilities. Professor Wojciech and his team are very good at what they do. My son has been training for over 5 years and he made tremendous progress in the last year after he started training at Hammer. Great gym, great people. Highly recommended”

“Wojciech and his staff are passionate about jiu jitsu and they have created a training atmosphere that is both intense and safe. This is a great place for both the beginner looking to start their jiu jitsu journey and the experienced grappler seeking high level training. Highly recommend Hammer jiu jitsu, see you on the mats.”

“Our son began training here when he was just 3 years old, and I truly can’t say enough about how exceptional this place is. The staff is not only incredibly skilled but also warm and welcoming, making it feel like a second home for our family. The entire facility is spotless, reflecting the pride and care they put into every aspect of the gym. The coaches and professors are top-notch—highly knowledgeable, patient, and deeply invested in each student’s progress. Whether you’re looking to advance your own skills or want your children to develop resilience, focus, and discipline, this is hands down the best jiu-jitsu gym in the Fairfield area. We couldn’t be happier with our experience here!”
