Meet the Coaches
Joel Costello - Black Belt

He’s won multiple Pan Pacific and Australian Championships, and was awarded his black belt on March 7, 2018 from Bruno Panno and Royler Gracie. He is a sponsored Hyperfly athlete and team member.
A Balmain boy, born and bred, Joel opened the academy in July 2016. He’s motivated and passionate about giving back to the community that’s given him so much.
Lachlan King - Brown Belt
Lachy found BJJ when looking for a new physical challenge after finishing his Rugby playing days, in his late 20s.
He says, “Although I was initially drawn to the sport’s physicality, I’ve grown to appreciate the mental intricacies the sport brings, and I think this is one of the main reasons BJJ is so addictive. I’ve been lucky enough to train at many different gyms around the world and by far the best aspect of BJJ for me has been the unique camaraderie you share with the guys/girls that you train with. Nothing beats the post-session chats with friends and strangers you’ve just tried to strangle. What a crazy, beautiful sport.”
What he loves most about coaching is seeing students take concepts he’s taught and making it their own by moulding it to their own style.

Rod is known for his passion in competition-focused training, emphasizing the importance of developing strong fundamentals for all members.
Gabe Bitti - Purple Belt
Leo Dadgostar - Blue Belt
My Brazilian Jiu Jitsu journey began when I was 16. I was training boxing/kickboxing next door to Gracie Balmain and I told my father in an offhand comment that I thought I wanted to try MMA. He looked next door and saw what Joel was teaching and sent me to learn.
This led to me falling in love with the Grappling arts. Becoming passionate about learning and sharing anything new I come across.
I eventually wanted to test what I've learned so far. Which led me to compete in the national wrestling competition in 2022, and my first BJJ competition in 2023 where I came 4th overall.
I love coaching because it keeps me thinking about the Grappling arts I enjoy. Guiding others to find their own solutions in this sport and seeing someone improve and/or progress their skills in BJJ.
