Adam Principato (Owner/Coach)

Welcome to Nirvana Brazilian Jiu Jitsu, where we believe in the art of mastering calm under pressure. My name is Adam Principato, and I’ve been passionate about Brazilian Jiu Jitsu and Judo since 2011. Over the years, I’ve had the privilege of training at some of the most elite schools, competing at high level tournaments, and, most importantly, building lasting friendships within the grappling community.

Brazilian Jiu Jitsu has had a profound impact on my life, both physically and mentally. It has helped me develop strength, flexibility, and endurance while also teaching me the importance of discipline, resilience, and staying calm under pressure. The mental clarity and confidence I’ve gained through Brazilian Jiu Jitsu have been invaluable, not just on the mats but in every aspect of my life.

I am continuing my own training at Mau Mau Brazilian Jiu Jitsu (a GFTeam affiliate) , to refine my skills and stay connected to the Brazilian Jiu Jitsu world. This ongoing training allows me to bring fresh perspectives and techniques to Nirvana Brazilian Jiu Jitsu, ensuring that our students receive the most up-to-date and effective instruction.

Now, I’m thrilled to bring my experience and love for Brazilian Jiu Jitsu to the city of Melrose. At Nirvana Brazilian Jiu Jitsu, we’re more than just a gym—we’re a community dedicated to growth, respect, and the pursuit of excellence on and off the mats. Whether you’re a seasoned competitor or stepping onto the mat for the first time, our goal is to help you discover your potential and find your inner strength.

Join us at Nirvana Brazilian Jiu Jitsu, and let’s embark on this journey together.

Kru Dave (Coach)

Kru Dave brings over 30 years of experience in Boxing and Muay Thai. His journey began in his early teens at the Somerville Boxing Club, where he honed his skills before training at various other boxing gyms around Boston. He eventually found his way to the renowned Sityodtong Muay Thai Academy, where he studied under Kru Mark Dellagrotte. There, Kru Dave had the privilege of training alongside Muay Thai fighters from Thailand and beyond, deepening his expertise in the art.

After years as both a student and coach at Sityodtong, Kru Dave returned to the Somerville Boxing Club as a coach, working with professional fighters, amateurs, kids, and weekend warriors alike to help them achieve their goals. He has participated in seminars with Muay Thai legends such as Coban and Ajarn Chai Sirisute, further expanding his knowledge and refining his teaching.

Kru Dave has also shared his expertise with numerous schools and academies throughout the Greater Boston area. His strict focus on technique has been instrumental in helping students progress rapidly and guiding fighters to success in the ring and cage. Beyond Muay Thai and Boxing, his passion for martial arts has driven him to study various disciplines, including Sanda, Dutch Kickboxing, Wing Chun, Escrima, Jeet Kune Do, Savate, Brazilian Jiu-Jitsu, and Silat.

As a competitor, Kru Dave fought approximately 10 bouts—mostly amateur, with a few professional-level unsanctioned matches—and emerged victorious in all of them. His combination of technical precision, experience, and dedication makes him a respected and effective instructor.
