 Marc Barton

Marc is a lifelong martial artist, starting at a young age with ninjutsu, and then Shotokan karate in his late teens. He trained in this for many years, achieving a 2nd Dan 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 2006 when he discovered the Roger Gracie Academy in London. 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 is also one of a small number of black belts personally mentored by the legendary Mauricio Gomes, who introduced BJJ to the UK in the early 2000s and is the father of the legendary Roger Gracie.

Marc now runs Jiu Jitsu Brotherhood London and teaches many of the classes. 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.

Marc is also a qualified doctor and was recently appointed as the medical officer for the UK governing body for Jiu Jitsu, the UKJJF.

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 was recently appointed as the head referee of the UK governing body for Jiu Jitsu, the UKJJF.

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. Alan is also available for one-to-one private lessons – contact us if you would like book one.

 


Andreas Wichmann

Andreas

Andreas came to Jiu Jitsu via training in Muay Thai and grappling in his early thirties in 2003. 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 is our competition team captain and organises our extra pre-competition preparation classes. He was awarded his brown belt by Marc and Nic in July 2018.

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.

 


Clare Barton

Clare has been practising martial arts for over 20 years, starting with Shotokan karate whilst at University in 1997 and gaining her 1st Dan black belt in 2001. She also travelled to Japan with Marc to train at the Shotokan Headquarters in Tokyo for 3 months in 1999.
