Moved to Hemel just over 2 years ago, and one of the best things I've done is join Mamba BJJ. The gym has a friendly and inclusive environment, and you feel a part of a team. It has high level black belt coaches that teach Gi, and no gi. I've also brought my daughter to the kids' classes, and she is now a full-time member. She loves the classes and always has fun and has made some good friends also. Highly recommend Mamba.
