    • I started training BJJ at Mill Hill combat and conditioning in London England.
    • I travel to Thailand to further my combat experience and after a crash course in Maui Thai fought at Phukets Bangala stadium.
    • I moved to Australia shortly after and trained under Daniel Lima in the Gold Coast.
    • I moved to Sydney and continued training under Bruno Panno.
    • I started teaching BJJ in Sydney and soon made the move to Brisbane and joined the Infinity team.
    • To instruct under the guidance of Prof. Neil Owen was an easy decision as he was highly regarded by my original instructor Nick Brooks (Roger Gracie Team), back in England.


    • As my BJJ journey continues my passion changes.
    • I started with a passion for submissions usually from the top position.
    • I then found sweeping most gratifying.
    • After a couple of years working from the bottom I found a new passion, Takedowns.
    • The beauty of BJJ for me is the endless dimensions.
    • My current passion is flying submissions!
