Professor David Ginsberg

Professor Dave GinsbergDavid Ginsberg is a 4th Degree Black Belt in Brazilian Jiu Jitsu, ranked by the legendary Master Mario Sperry. Professor Ginsberg (“Coach Dave”) is amongst the highest ranking Americans in the Northeast, as verified by the USBJJF and IBJJF. He has been a full time BJJ and MMA instructor since 1997 and coached gymnastics and fitness as far back as 1988. He was the first or among the first New Englanders to receive a Black Belt in BJJ (2003), to win back to back Gold Medals in The Pan American Games of Brazilian Jiu Jitsu (2002 & 2003), to win multiple matches and medal on the Black Belt Level in International Competition (2004), to coach a student to a World Title at the IBJJF World Championships, to be appointed as a licensed MMA official in Massachusetts, and to judge a UFC Title Fight. Coach Dave also owns numerous NAGA, New England and Grappler’s Quest No Gi titles from 1996 to 1999. He has trained Olympians in Judo and Synchronized Swimming and professional athletes including NBA player Glen “Big Baby” Davis.

Coach Dave’s martial arts teaching style is informed by his background in gymnastics and dance and his degree in Buddhism & Creative Writing. In gymnastics, he is a title-holder on the still rings & floor exercise & he was coached, over the course of a decade, by 3 Olympic coaches. His academic studies included numerous merit-based scholarships and coursework at Oxford University, The Central Institute for Higher Tibetan Studies in Sarnath, India and Amherst College, and culminated in his graduating Summa Cum Laude from U Mass Amherst, and he was granted membership into the country’s oldest honors society, Phi Beta Kappa. Coach Dave believes in tailoring martial arts, techniques and movement to suit the needs of the practitioner, and he is honored to be a part of the wellness and self-empowerment process of individuals who are starting a martial arts practice or hobby for the first time as well as lifelong martial artists.

Coach Dave’s extensive personal experience in competitive athletics and his interest in wellness, spine and joint health and longevity have led him to develop close professional relationships with many in the Sports Medicine Community including a leader in his field, Jake Kennedy. He believes that more important than the short gain of a great martial arts technique or fitness circuit is that one’s martial arts practice be conducive to long term health and injury-prevention. Longevity, healthy posture, and knee, spine and shoulder health are of utmost importance on the mats and off. Coach Dave’s personal philosophy on competing is that it is for those who chose to challenge themselves in that way, but it is by no means a requirement or something that people should be pressured to do. His personal philosophy on MMA is that it is for those who are drawn to it and have a deep desire to compete in it; and although he enjoys training lightly and with control, he has never been interested in competing on a high level because it goes against his personal practice of non-violence.
