I've trained at multiple academies over the years, and Jimmy stands out as one of the most detail-oriented instructors I've met. As a Brown Belt, his technical knowledge is top-tier, but it's his ability to teach that sets him apart. Whether you're fine-tuning your guard or developing your pressure passing, Jimmy knows how to take your game to the next level.

Jimmy is a true asset to our academy. His leadership on the mat, attention to fundamentals, and ability to connect with students at all levels make him an outstanding instructor. As a Brown Belt, he sets the standard for professionalism and continuous growth.

I’ve had the pleasure of being coached by Jimmy during my Physical Training Instructor course, and I’ve also had the privilege of rolling with him on the mats in his Jiu-Jitsu classes.

What stands out about Jimmy is that he doesn’t just coach - he lives it. He’s the definition of someone who practices what he preaches.

His passion sets the standard high, and when you’re under his wing, there’s no room for half measures. You’re expected to show up, dig deep, and operate at your highest level.

Jimmy has a rare ability to read people and quickly gauge what they’re truly capable of, and he’ll push you to reach nothing less than your gold standard.

If you’re serious about unlocking your potential and want a coach who genuinely brings out the best in you. Jimmy is your man.

Coach, Jimmy, absolutely incredible, martial artist, leader, and instructor. Welcoming to new Jiu Jitsu practitioners of all levels with the ability to engage deeply on and off the mat. His attention to go deep into details without confusion is outstanding. Willing to stay at competitions to ensure his student had a coach in his corner, not just for his first match, but for all four throughout the day. Dedication to his family, his work, and the art of Jiu Jitsu is hard to emulate. Incredible man, father, instructor, and leader. Roll model for young men

My friend, Jimmy, has been an invaluable training partner and coach. His dedication to the sport is evident in every roll and drilling session. What truly sets Jimmy apart is his ability to explain complex techniques in a clear and understandable way, breaking down movements so they're easy to grasp. He has always pushed me to improve, offering constructive feedback, and encouragement, whether we're drilling new submissions or getting in rounds. I'm especially grateful for his support and guidance during competition prep. His insights and calm demeanour really helped me stay focused during my preparation leading up to the 2023 Master Worlds and No-gi Pans. Training with Jimmy has made me a better jiu-jitsu practitioner and has also deepened our friendship. Anyone looking for a knowledgeable, supportive, and truly dedicated training partner would be lucky to have Jimmy on the mats.

I’ve had the privilege of learning from Jimmy both professionally and on the mats, and I can say without hesitation that Four5’s is going to be something special.

Jimmy’s background as a Royal Marines Physical Training Instructor is the foundation of his world-class coaching style. The discipline, structure and clarity he honed in one of the most demanding military roles translates seamlessly into the way he teaches Jiu Jitsu. Every class is delivered with precision, purpose and a deep understanding of how people learn best.

What truly sets Jimmy apart is his ability to simplify complex techniques and communicate them in a way that actually sticks. His coaching is clear, methodical, and patient - making even the most technical movements feel accessible. Whether you’re brand new to the sport or years in, you’ll walk away from every session with something valuable.

On a personal level, Jimmy has been a mentor to me throughout my own journey as a Royal Marines PTI. His influence has shaped not only the way I coach, but the way I approach learning, leading and thinking. His depth of knowledge, passion for the sport and commitment to those around him is second to none.

Four5’s is going to be a place where excellence is built and I couldn’t recommend Jimmy or his coaching more highly.

I’ve had the privilege of being coached by Jimmy in boxing and also benefitting from his guidance in Brazilian Jiu-Jitsu. His influence has been a huge part of my development in both disciplines. Jimmy leads by example—he’s constantly pushing himself to improve, and that drive for excellence naturally extends to the people around him.

I’ve also had the pleasure of competing alongside Jimmy in BJJ, and his presence on the mats is always inspiring. He doesn’t just train athletes—he produces high-level, well-rounded individuals who carry themselves with discipline and intent. Whether he’s cornering, coaching, or competing, Jimmy brings out the best in everyone around him. His standard is high, and he helps others rise to meet it.

I’ve had the pleasure of attending a few classes taught by Jimmy and they’ve all been great, super informative and broken down in a way that even a day one white belt could get it. I’ve learned a lot from him, not just moves but some important concepts and techniques that have helped me really improve my Jiu-Jitsu. Thanks Jimmy!

I was first exposed to BJJ during my Royal Marines Close Combat course. Having never done anything like it before, the way Jimmy taught me made it not only easier to grasp, but made it enjoyable. It is evident he is incredibly passionate and experienced in the sport and his ability to teach in so many different ways for people who have no to a lot of experience makes him a great asset in the BJJ coaching and teaching world”

Jimmy has a fantastic reputation in the British grappling scene, both as a competitor and coach. His concise and direct approach to teaching, which is consistent with his background as a Royal Marine, gives students of all levels the ability to understand highly technical details with relative ease. Jimmy’s knowledge of the sport, along with his work ethic and charisma make him an outstanding coach and training partner.

I've had the privilege of training with Jimmy throughout my jiu-jitsu journey, and I can honestly say that his guidance and level of knowledge has made a massive impact on my growth on and off the mats.

From the beginning, walking in as brand new white belt he demonstrated an incredible ability to break down techniques in a way that made them easy to understand and apply. Diving into more advanced concepts, Jimmy always took the time with all students to explain and give a little confidence along the way.

Jimmy has a huge amount of experience in Gi and No-gi as well as countless competitions. From a white belt who's only been training for a year or so, the bloke is really approachable, he explains things in a way that's really easy to understand and he's very open with what works and what doesn't at competition.
