David Marinakis
Brazilian Jiu Jitsu Coach (Black Belt 1st Degree)
“I got introduced to BJJ back in 2003 after watching the early UFC’s and Gracie in Action tapes (you can still find some of these on YouTube). Basically these tapes showed these smaller statued Jiu Jitsu guys defeating all these larger opponents from other martial arts backgrounds. I felt like I had stumbled upon the holy grail of martial arts! I was looking for something to train in and wasn’t interested in doing Kata’s or ‘Forms’. I wanted something more real, practical, challenging, and Jiu Jitsu met that need for me. In 2005 when I found the right training environment, I fell in love with Jiu Jitsu and never looked back.”
BJJ Accomplishments:
“My proudest accomplishments to date have been representing Australia twice at the ADCC Submission Wrestling World Championships in both Barcelona, Spain (2009) and Nottingham, UK (2011) where I got to compete with 2 of my idols, Rubens ‘Cobrinha’ Charles and Leo Vieira.
I have also qualified twice to represent Australia at the World Pro Jiu Jitsu Championships held in Abu Dhabi, bringing home a bronze medal in 2011, Brown & Black belt division.
In 2015, I completed a 10 year goal of winning a State and Pan Pacific gold medal at every belt level when I won the Victorian and Pan Pacific Championships at Black Belt.
Coach Lee and myself both teach the BJJ classes at Immersion meaning there’s 2 black belt coaches on the mat every night! We’d love to have you join us so we can share our Jiu Jitsu with you.”
