Why Did You Start BJJ?

It was a game changer and revolutionized martial arts. At the time I was training JKD and Thai Boxing and found out how ineffective they were without a ground game.

How Long Ago?

It’s over 20 years ago now. I started with Craig Kukuk and Renzo Gracie when they opened their schools in New Jersey.

Why Did You Start BJJ?

I had wanted to box, but after doing it for 1-2 months I discovered I was terrible at it and kept getting injured! I still wanted an alternative to working out at the gym ‘lifting weights and doing cardio’, so my best friend Roy Duquette turned me on to ‘Groundwrestling’. I started with Sambo, then moved onto BJJ shortly after.

How Long Ago?

I started BJJ in 2001.Continue Reading

Why Did You Start BJJ?

I had trained in other martial arts and felt that if the individual I trained with was larger he would always have an upper hand. When I found Jiu Jitsu I found an art that could neutralize anyone.

Why Did You Start BJJ?

I credit Mike Pandolfini 100% with getting me started in the martial arts. He’s been training in a variety of disciplines since we were in high school, and he was always looking for partners to train with in his basement and backyard. After years of asking, I finally took him up on it and starting taking BJJ classes during law school so that we could train together after graduation. Really no deep rhyme or reason as to why I started. During my teens and 20s, I got into a lot of street and/or bar altercations for no good reason and had a fascination with combat sports and the fighting arts. Just wanted to be better equipped than the next guy.Continue Reading

Why Did You Start BJJ?

I was a Bruce Lee fanatic. I always loved martial arts growing up; however, I played 3 seasons of sports so I never had the time. My senior year of high school after basketball season was over I decided to pursue Martial Arts. I did not know where to begin, so I opened the Yellow Pages and saw “Shaolin Kung Fu”. At this time the rap group Wu Tang Clan was a big hit so I thought that this was destined to be the place (lol).Continue Reading

We look forward to training with you.

Student– Princeton BJJ

I've been at 4 academies, and Princeton Brazillian Jiu Jitsu is by far my favorite. Emily Kwok and Art Keintz are inspiring, the focus is on learning and performance, a large number of partners participate in competitions and receive lots of support from the members and professors, and all of the instructors are expert. There is a healthy balance of men and women, and the practices are a good mix of respectful training and safe sparring. The dojo is part of the Marcello Garcia association, and Art and Emily awarded legitimate Black Belts to two students last year. This Academy is special!

Student– PBJJ

I am extremely happy to have started my BJJ journey with Art and Emily at PBJJ. It’s clear to see from all of the instructors that BJJ is more to them than just a martial art and that directly translates into the culture at the gym and the attitudes from students. I originally started because I thought it was interesting. I continue to train there because the instructors are top notch, the mats are clean, and the community of students that I train with make me feel at home.
