Steven Crocilla Jr.

While in the processing phase of his NYPD application in 2007, Steven was struck by a car as a pedestrian suffering four herniated discs in his back. After being told he would never exercise again, he gained 70 pounds and stopped physical therapy. Luck would have it that a friend got him into a Jiu-Jitsu class, and after taking his first class he knew he found his place. Losing the excess weight Steven became a fixture in the school. He began instructing as a White Belt, unheard of in most schools, but that allowed him to hone his skills faster. Steven trains daily to get to the highest level, and is proud to hold the rank of Black Belt under Fabio Clemente. In order to be a well rounded coach Steven has also trained in Muay Thai kickboxing with a World Champion instructor for the past few years and currently takes private lessons in Western boxing with Olympic boxer and Coach, Carlos Motta.


John Carter

John started Brazilian Jiu-Jitsu in 2014 with team PSABJJ. As a Park Slope native he wanted to get better fitness and an understanding of grappling. John soon became a fixture on the mat, training consistently and also competing. You will see John training typically six days a week and often helping out in any of our beginner classes.

Dante started with Professor Crocilla and Professor Adami when he was just 10 years old. Now, he is an assistant instructor for Little Grapplers and Junior Grapplers classes.
