The coach that I take lessons from, Ovi, is hands down one of the best coaches I've ever had the opportunity to work with, in any sport that I've ever participated in.

Professor and all of the instructors here are phenomenal. They provide a great level of detail and clarity. They tell you what it should look like, how it should feel, where you should shift your weight. They also adjust according to your level and ability, even when there's like 20-30 other students. The environment and other students also make this gym awesome. I've been to some other place where students just want to demolish you, even if you're a lower belt. Most experienced students here will adjust their strength when you roll with them and will guide you along, especially if you're newer. When people get better, I've noticed they pass this along as well. On the flip side, if you want to go up against someone really good, you have plenty of options here. If I ever move back to Boston, I'll definitely come back here to continue. Seriously the best BJJ gym in the city! Easily 5 stars!

Shortly after, we requested a membership freeze (which they confirmed in writing), and later submitted a cancellation request that they also acknowledged. Despite both the freeze and cancellation being confirmed, they continued to charge us. We reached out multiple times over several months to resolve the issue. At one point they acknowledged the problem and said refunds were being processed, but the charges continued. We ultimately had to change our credit card number to stop the billing. It's unfortunate, because the program itself seemed good and our kids enjoyed it.
