Meet Your Coach
Rob Olivier
Head Coach · BJJ Black Belt
Rob's journey in martial arts and combat sports has been a lifelong passion. He started with Judo at the age of six and achieved his judo Black belt in 1998. From 2002 to 2014, known as Robbie "the Flame" Olivier, Rob concentrated on MMA, competing professionally in 32 fights and securing numerous national and international titles including Cage Rage and WFC. A Brazilian Jiu-Jitsu Black Belt, Rob's expertise isn't limited to MMA; he has also been actively involved in BJJ and grappling as a competitor and coach, sharing his knowledge with athletes worldwide, including those in the UFC.
My goal is simple — create a place where people can learn, improve and thrive on and off the mats.
