Marc has a wealth of experience in the martial arts world, starting at a young age with ninjutsu in South Wales. Like a true Welshman, rugby took over for a while, but then he discovered Shotokan karate. He trained in this for many years, achieving a 2nd degree black belt. Karate also inspired travel to Japan where he trained at the Shotokan Headquarters in Tokyo for three months in 1999.

Brazilian jiu jitsu became a new focus in 2007 when he discovered the Roger Gracie Academy in London. Marc trained here regularly for several years and this is where he first met Nic Gregoriades and has continued to train with him ever since. Marc was awarded his black belt by Nic in December 2016.

Marc now runs Jiu Jitsu Brotherhood London and teaches many of the classes when Nic is away. He has also introduced a highly successful kids programme in Kingston, and has loved the chance of introducing jiu jitsu to his children. Jiu Jitsu Brotherhood and its ethos are now an integral part of Marc’s life.


Oliver Geddes

Oliver Geddes

 

Oliver Geddes is a Brazilian Jiujitsu black belt under 10-time World Champion Roger Gracie. He began training at a local school in 2005, but quickly moved into London to train at the famous Roger Gracie Academy. From this base he settled into training full-time, eventually receiving his black belt in December 2011 after a little over 6 years of hard study.

Since then, he has spent time travelling, training and competing all over the world, always looking to further his knowledge with new partners in new locations.

Oli now teaches regularly at JJB London when not travelling the world to teach and compete.


Alan Kentish

Alan is one of our most experienced grapplers and instructors, holding a black belt in Judo for over 20 years in addition to a brown belt in Brazilian Jiu Jitsu. Alan is currently a 2nd Dan black belt in Judo under the British Judo Association (BJA).

His unique perspective of both arts has enabled him to isolate the takedowns and stand up work that he feels is most relevant to BJJ practitioners. Alan regularly teaches our ‘Judo for BJJ’ sessions on Wednesday evenings.


Andreas Wichmann

Andreas

 

Andreas came to Jiu Jitsu via training in Muay Thai and grappling in his early thirties. Due to work commitments he took a break for a few years but returned to Jiu Jitsu in 2015 in order to get in shape for his wedding. He hasn’t left us since, and apparently you can teach an old dog new tricks as he won a Gold medal in the NAGA No Gi competition, as well as Silver and Bronze medals in IBJFF, NAGA and the Surrey Open Gi.

Andreas’ attention to detail style of teaching helps our beginners get up to speed quickly and understand the basic concepts of BJJ. He also very much enjoys stretching and yoga and emphasises it in his warm ups, having learned the hard way how important flexibility is.
