Coach Fernando Restrepo

Coach Fernando “Reals” Restrepo is a Vitor “Shaolin” Ribeiro Brazilian Jiu Jitsu Black Belt. He has trained in martial arts for over 15 years and has dedicated the better part of the last decade to his study of Brazilian Jiu Jitsu. After graduating from Binghamton University, while working on a Masters in the Science of Teaching at the New School, he dedicated himself to training diligently in Jeet Kune Do concepts. That is how he discovered the grappling art of Brazilian Jiu Jitsu that would become his lifelong passion. Through hard work and dedication he earned his belt in November of 2017.

As an educator and proponent of Jiu Jitsu he has taught Brazilian Jiu Jitsu throughout the city most notably, through a social project for public school students in The Bronx since 2011 and he came to lead the Brazilian Jiu Jitsu program at Unlimited Martial Arts after teaching the BJJ fundamentals course and helping grow a successful competition team at Bronx Jiu Jitsu for four years. He is excited to do the same here in Brooklyn.

Coach Fernando prides himself mostly on teaching beginners, helping grow a love for the art, and coaching aspiring Jiu Jitsu athletes to compete. Most notably he coached the Bronx Jiu Jitsu competition team to a second place team trophy at the 2016 Big Apple BJJ Open. However, he has competed a bit himself and as a purple belt he attained a gold medal at the CSBJJF fall 2014 tournament, a gold medal at the CBJJD-Mineirinho 2014 held at the world famous Tijuca Tenis Clube in Rio, and a silver medal at the IBJJF Boston Summer Open in 2012.
