I highly recommend this BJJ studio. Professor John teaches much more than just self-defense and…read morejiu-jitsu skills. He shares important life lessons that go beyond the mats. He emphasizes to the kids the importance of following rules, whether you like them or not, because structure and discipline create order in the world. He also teaches that winning and losing are both part of life -- what matters most is how you bounce back and keep improving. Training BJJ has helped my kids grow not only as a martial artist, puts them back and humbles them. - Also plenty of mat time for the kids, in every group age and levels. They always have partners their age and size.
