I've been at Dragon Gym for a year, mainly for their BJJ classes. It's an amazing community where everyone, from beginners to advanced practitioners, shares a passion for learning and improving in BJJ. I still remember my first class, when a purple belt partner successfully introduced me to the sport.
The instructors are knowledgeable and always supportive.
Another perk is the option to train at other Dragon Gym locations like Exton and Berwyn, giving you the chance to roll with people of varying skill levels.
I absolutely recommend Dragon Gym.
