Hammer Jiu Jitsu

“Hammer Jiu Jitsu is a great place! Both my 11 and 7 year old children attended classes! They are kind, friendly and very patient with the children. They even did check ins when the kids missed classes which shows that they care. My children enjoyed their time here and just decided that they wanted to try something else. I would highly recommend Hammer to anyone! They are great!”

“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.”

“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!”

“Hammer is a top tier school. The instructors are both welcoming to newcomers and highly skilled in the sport. The community is full of caring and passionate people who are eager to learn. Hammer is the BEST place you will find to jump into the world of BJJ.”

“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”
