What Our Students Say

Christopher Mancuso
"What an excellent gym, this place completly changed my life around. Met great people, lost 50 pounds since I started, and just put me in a more positive direction in life. This is the perfect place for newcomers and people who have been training for a while. Coach Matt is the man."
Ryan Coyne
"I first trained under Matt when he taught his fundamentals class at Vamos MMA. It’s obvious that there was a true passion for not only bjj- but also teaching it. I saw immediately that this wasn’t just about training. Some of the conversations we’ve had after class has changed the course of my life, undoubtedly, for the better. After a 5-year break, I came back to train at the jui-jitsu Den. I was welcomed with open arms and thrown right into the mix with fellow students who I’ve grown to love. The school breathes a culture that is built from mutual respect for one another, grit, and a love for the art. I feel incredibly grateful to be able to train, I feel especially grateful to be training at the Den! “Time flies, you might as well train.”"
Bryan Mendez
"Although our lives once ran in different circles—Matt graduating High School in 1998 and me in 1999—our paths finally converged in 2016 when I began my Jiu-Jitsu journey. Since then, Matt has become much more than an old acquaintance; he’s evolved into a trusted friend, mentor, coach, and training partner. I also consider him part of my family—a true brother in every sense. His unwavering generosity and expert guidance have made all the difference, no matter the challenge. As a Designer, collaborating on the logo for The Jiu-Jitsu Den in Bellport, NY was an absolute pleasure, and every time I step onto the mats at The Jiu-Jitsu Den, I’m embraced by a community that embodies humility, grace, and a genuine passion for the art. Whether you're aiming to compete or simply train for fun, Matt’s steadfast support and heartfelt commitment shine through. He is truly one-of-a-kind—both on and off the mats—and I wholeheartedly endorse him and his exceptional school."
Rick Drnek
"My daughter and I have been training at the Jiu Jitsu Den with coach Matt since it opened. It’s a great environment for everyone, from beginners to competitors. The kids class is excellent, Coach Matt and all of his other coaches are knowledgeable and very patient. The adult class is growing quickly for the same reasons. I highly recommend the Jiu Jitsu Den for anyone wanting to start or looking for a new gym experience."
