"My son started at Dragon Gym two summers ago and since then I’ve been blown away by the kindness, devotion, and expertise that the coaches embody with the children. Master Joe is a truly a master on so many levels. His ability to connect to his students with compassion and still maintain a structured and orderly class is unparalleled. The rest of the staff is wonderful as well. Everyone is so helpful and kind. My son has benefited so much from the confidence and discipline that is being instilled in him through the precepts taught by Dragon Gym. I can’t sing their praises enough. We love Dragon Gym!"
"Our three boys (twins, age 4, and their 7-year-old brother) absolutely love Dragon Gym! From day one, the instructors have been amazing—patient, engaging, and truly invested in each child's progress. They create a fun and supportive environment while teaching discipline, focus, and confidence. It's been incredible to watch our kids grow, both physically and mentally, through their martial arts training. They look forward to every class, and we love seeing their excitement and improvement. If you're looking for a top-notch martial arts program for kids, Dragon Gym is the place to be!"
"I’ve been training at Dragon Gym Mainline for about a year now, and I can’t recommend it enough! From the moment you walk in, you’re greeted by friendly and welcoming staff who make you feel at home. The students are just as inviting—everyone is respectful, supportive, and always willing to help, whether you’re a total beginner or an advanced practitioner. A huge part of what makes this gym stand out is the head instructor, Tom Palmer. His jiu-jitsu skills are top-notch, but what really sets him apart is his ability to teach students at all levels. Whether you’re new to the sport or looking to refine advanced techniques, he breaks things down in a way that’s easy to understand and apply. He creates an environment where learning is both challenging and fun, making every class something to look forward to. Dragon Gym Mainline is also a great place for women to train. In a male-dominated sport, it’s not always easy to find a gym where you feel safe and supported, but this gym is truly welcoming for women. The instructors and students foster a respectful and inclusive atmosphere that makes training both fun and empowering. If you’re looking for a high-quality jiu-jitsu gym with excellent instruction, a welcoming community, and a great atmosphere, Dragon Gym Mainline is the place to be. I’m grateful to be part of such a fantastic team!"
"Dragon Gym Berwyn is an excellent martial arts academy with expert instructors. They are especially great with the Pee Wee and Junior groups. Adult groups are supportive and have great camaraderie here. Great off street & ample parking available at their new location!"
