Hailing from Teresópolis in Rio de Janeiro, Brazil, Vitor brings over two decades of world class Jiu-Jitsu experience to Ronin. He immersed himself in training at the legendary Pitbull Academy when he was only 8 years old. Following in his father’s footsteps, he earned his black belt from Adilson de Lima at the age of 22. Since receiving this highly respected rank from one of the world’s top BJJ instructors, Professor Oliveira has joined Grappling Fight Team as a renowned coach and competitor. In addition to sharing his love and knowledge of BJJ with both children and adults, he remains an active competitor in some of the world’s most prestigious Jiu Jitsu tournaments. When it comes to teaching BJJ, you won’t find a more qualified instructor than Vitor. And while he loves to see his students excel in tournaments, what he loves the most is the progress each student makes as a result of hard work and determination. As a two-time World Champion with dozens of high-level titles, Vitor is more than qualified to teach BJJ to all students willing to learn. Some of his more recent accomplishments include:

Coach Boggs has traveled the globe to sharpen his martial arts skills, learning under some of the world’s most talented strikers. Starting as a student of Tae Kwon Do more than 20 years ago, he’s since trained in boxing, Wushu, Kum Do, Judo and Muay Thai. Boggs spent 5 years in Asia, learning under the tutelage of masters like Champ Oh Seong (Korea’s National Muay Thai Champion) and South Africa’s Kobus Huisamen (Kickboxing Champion and Pro MMA Fighter). It was during this pilgrimage that Boggs was introduced to Muay Thai, and finally found the exact striking art he had been looking for.
After two decades of training and perfecting his craft, Coach Boggs has settled back in Ohio. He’s brought technique and experience from all over the world right here to Ronin, and he’s eager to share what he’s learned with others. Back in the U.S., he’s studied with legends like An Tian Rong, Neal Rowe, Saekson Janjira and Samart Payakaroon.
Coach Boggs is equipped with years of unparalleled experience, bringing a level of Muay Thai and striking instruction to Ohio that you won’t find anywhere else.
