Owner & Head Instructor

Jon is the founder and head instructor of Kent Grapple, holding a 1st Degree Black Belt in Brazilian Jiu Jitsu. Kent Grapple began at Swale BJJ before growing into the full-time academy it is today — and Jon has been at the heart of that journey every step of the way.

Dave Chapman
2nd Degree BJJ Black Belt

Dave Chapman

Instructor

Dave is a 2nd Degree BJJ Black Belt with nearly 20 years of grappling experience — one of the most seasoned practitioners you'll find on any mat in Kent. That depth of knowledge is something you feel the moment you roll with him; every position, every transition, every detail carries the weight of genuine mastery built over two decades on the mat.

While Dave doesn't run a fixed weekly class schedule, he's a regular presence around the gym in the evenings and takes the Thursday 8pm session — an opportunity for members to learn directly from one of BJJ's most experienced practitioners. If you get the chance to pick his brain or get a round in with Dave, take it.

Trevor Harris
BJJ Brown Belt

Trevor Harris

Instructor

Trevor is one of Kent Grapple's original members — he was there from the very first session at Swale BJJ, before the club had a home of its own. That founding spirit runs through everything he does on the mat. As a well-rounded competitor with experience across all ranges of BJJ, Trevor has built a complete, pressure-tested game that works at the highest level.

Now holding a Brown Belt, Trevor channels that competitive mindset directly into his coaching, running the Wednesday 6am session for those committed enough to chase improvement before the rest of the world is awake. His sessions are technical, demanding, and built on the same principles he's refined through years of competition.

Max Bartolo
BJJ Brown Belt

Max Bartolo

Instructor

Max holds a Brown Belt under Ross Nicholls and is one of those rare athletes who truly lives the BJJ lifestyle. When he's not coaching the Thursday No Gi session at Kent Grapple, you'll find him rolling at some of London's most competitive training venues — London Grapple and Los Banditos Club — constantly testing and refining his game against elite-level competition.

That commitment doesn't stop at class time. Max regularly opens the gym early so members can get in extra mat time before the day starts — a reflection of the dedication and generosity he brings to everything he does. His No Gi game is sharp, technical, and grounded in real competitive experience, making the Thursday evening session one of the most sought-after on the schedule.
