Lewis Matthews, Head Instructor

Rank: Black Belt

Professor Lewis Matthews is the head instructor and owner of Gracie Barra Harrogate, and has been training Brazilian Jiu Jitsu since 2006. He was awarded his black belt in December 2017 from world champion and head of Gracie Barra Europe, Professor Victor Estima. Professor Lewis is a keen competitor and enjoys testing the efficiency of his Jiu Jitsu under pressure; but his main focus is in spreading the benefits of BJJ to members and supporting them in achieving their own goals. He places a strong emphasis on developing sound fundamentals and utilising intelligent grappling over the use of physical attributes to ensure longevity in the sport. Lewis believes in the ‘Jiu Jitsu for Everyone’ approach and ensures that Gracie Barra Harrogate caters for all students, from hobbyist to competitor alike.

Khalil Bostan, Instructor

Rank: Brown Belt

Coach Khalil started training Jiu Jitsu in 2007 and is a long-time friend and training partner of Professor Lewis Matthews. He works in emergency services, as well as being a husband and father of three children, so is constantly balancing his responsibilities between home, work, and Jiu Jitsu. His Jiu Jitsu hero is Master Rickson Gracie, and he is a firm believer that everyone who trains should learn and practice the self-defence elements of Jiu Jitsu, as this is what separates Jiu Jitsu from other martial arts, and makes it a truly effective way to defend yourself from an aggressor! Coach Khalil regularly covers classes in our Adults programme but also leads the midweek GB Kids classes.

Luke Craggs

Rank: Blue Belt

Luke joined Gracie Barra Harrogate in 2016 as a white belt, new to Brazilian Jiu Jitsu. He immediately fell in love with the art and since joining he has committed to training daily, completing his instructor certification in late 2018 to assist with the GB Kids programme as well as representing GB Harrogate at a national competition level. His youth and enthusiasm for Jiu Jitsu is a huge asset within our GB Kids programme, where he has developed his teaching style to effectively communicate complex techniques to our younger members.

Phalana Mokalake

Rank: Blue Belt

Phalana joined Gracie Barra Harrogate in 2016. After receiving his blue belt, he completed his instructor certification in order to help in the GB Kids programme and run our midweek daytime GB1 classes. He has a solid understanding of the fundamentals of Jiu Jitsu and is also a fully qualified Yoga instructor, so likes to incorporate health and flexibility into his teaching. Working within our GB Kids programme is where coach Phalana’s passion for Jiu Jitsu and teaching really shines through.
