Kyle O
"I moved to New Jersey after graduating college and starting a new job. After several months of coming home from work and having nothing to do, I decided to try out a new sport by joining this gym. This was one of the best decisions I’ve ever made. Danny and the coaches not only provide excellent instructions through traditional and modern approaches, but they also facilitate a culture of camaraderie and peer-to-peer learning. Attending class became a way to learn new techniques while also hanging out with the new friends I have made. Thank you to NJ Ronin and the team for providing me with a new home while away from home."
Adam Nixon
"This gym has such so much to offer, a great variety of classes, culture is excellent, and there is tremendous support if you want to compete in BJJ. The owner does an excellent job making sure that the gym has a very. This is the second gym I've been to, and while I liked my first gym years ago, this one has been the perfect fit for me, I can't get enough of it. I have not had a bad day once here, the training is awesome. Besides being extremely newcomer friendly and having a great culture, I would say the owner's one quality that separates him from the rest is that he's willing to adapt the techniques that he teaches extremely fast. He's still a student of the game as well and he'll go out to other places and learn new techniques and is quick to share them with us and they help so much."
Arthur Georges
"Nj Ronin is not only a great training facility for bjj, muay Thai, and other forms of self defense and combat. It is a welcoming community full of inspiring dedicated individuals that welcomes new comers and beginners with open arms and makes them feel wanted and at home. Everyone is willing to help guide you through different techniques and are often open to sharing their own combat styles and why it suits them. The coaches are fantastic and the man running the show Danny is always looking out for everybody and providing them with the knowledge and tools to excel in whatever goals you have for martial arts training. The best part is that even beyond the training everyone here gets along great and the atmosphere that is present here starts from the top on down with Danny and his comforting nature."
