Owen Gee Kee

Owen began training Brazilian Jiu Jitsu in 1997. At that time in Queensland he was learning from one of only 2 Blue belts teaching the Brazilian Jiu Jitsu in the state. In 1999 he moved to Sydney and then restarted training Brazilian Jiu Jitsu in 2001 under Bruno Panno of Gracie Humaita.

Learning directly from Bruno Panno, Marcos Nevel and Alex Prates; Owen received his Black belt in 2013 and is currently a first dan.

Cameron Lane

Cam has been training Brazilian Jiu Jitsu since 2010. At the time he was 17
when he began with no previous martial arts experience. Shortly into his Jiu
Jitsu journey, he also began freestyle wrestling under the then Australian
national teams coach to help increase his offensive grappling skills.

Cam previously trained under Alex Prates at multiple sites across Sydney,
but has been training under Owen and Sarah since Gracie Humaita Miranda
opened. He has been honing his coaching skills over the past 12 months, and
is currently a brown belt, 3 stripes.

Cam is excited and open to sharing his grappling knowledge to help those
that join the Gracie community and looks forward to meeting all that step on
the mats.

Chris began Brazilian Jiu Jitsu in 2009 at 12 years old and has a wrestling, boxing, MMA and Muay Thai background as well where he has fought amateur and professionally. Chris has lived in the Sutherland shire his whole life and began Jiu jitsu here under Alex before migrating to coach at Gracie Humaita Artarmon, Gracie Humaita Smeaton Grange and currently Gracie Humaita Miranda under professor Owen GeeKee.

Chris has competed in Brazilian Jiu Jitsu internationally (Japan, Abu Dhabi, Rome Italy) and numerous times on the local circuit in Australia when coach Owen has been in his corner.

Brad Ku

Brad started his jiujitsu journey back in year 2000 when he and his teammate Owen were both white belts under their Coach Bruno Panno, Brad loved jiujitsu right from the start and decided to take it more seriously than just a hobby.

In 2001, Brad moved to Japan where he spent most of the training time polishing his techniques and expanding the understanding of the gentle art. In 2010, Brad received his Brown Belt from sensei Wado Toshiyuki (Founder of Checkmat Tokyo). He made a bold and decisive move to leave behind the security of a conventional job for 8 intense months of training in Rio de Janeiro, Brazil.

Fast forward to 2018, Brad moved back to Australia and reunited with Owen at his newly established academy, where he has been one of the instructors since then.
