NESF Boston

"Dave’s teaching and class structure is second to none! His grit and tenacity is an energy I have not seen exhibited at other gyms. He is willing to go the extra mile to make sure I fully comprehend a technique or concept. As long as I’m around I will always train at NESF!! Dave is the man!!"

"I first began training underneath Dave Roy during college in my time out in Amherst. When I heard he was opening a new location closer to Boston, I was prepared to drive 30 minutes for the chance to train underneath him again. When I found out the location was about a mile from my house, I really had no excuse to not go. Dave Roy’s investment in his students is unparalleled. The time, effort, and attention to detail he puts into your improvement in training is something that makes you want to work even harder and continue to grow in the martial arts. On top of the excellent job Dave does instructing, he has built a welcoming environment that helps instill a hard work ethic and a competitive mindset. The facilities are clean, and the training is top notch. It is a great place for anyone in the greater Boston area who is looking to start training."

"This is a great gym wether you are just starting out or already experienced but looking to level up your grappling skills. Dave Roy is a very knowledgeable instructor with very crisp technique and teaches in a way that is accessible to everyone. Gym is also very clean. Highly recommend"

"Dave Roy is a great instructor with deep knowledge in MMA and Jiu-Jitsu. He gives personal attention to each student, and makes sure everyone gets the technical help they need. The facility is clean and has plenty of mat space. If you're in the Boston area, this is the place to train!"

"NESF Boston is one of the best No-GI Jiu-Jitsu gyms I have ever trained at. Dave is an amazing coach. How digestible his classes are while still giving such detailed instruction really speaks to the amount of time he has been teaching and the preparation he puts into every class. It is amazing to have a great No-GI school in the Boston area with high-level people who are also as welcoming as they are! The schedule is great. The facility is always clean. The showers give me the opportunity to train before I go out for the night. This place is one of a kind!"
