WHAT MAKES UP THE GORILLA GRAPPLERS?
GORILLA GRAPPLERS
Founded in 2021 by Adam Gunning, Gorilla Grapplers has one core mission: to build strong, disciplined, and technically sound combat sport athletes. At the heart of the academy is a belief in intelligent aggression, controlled technique, and constant evolution.
Gunning or Gunner as most now him, is a First Degree BJJ Black Belt under Jack Magee, a multiple tournament gold medallist, and has been a dedicated member of the Mad Hatters since 2014. With well over a decade in combat sports, his journey began with Kickboxing and MMA at Carter’s Combat Centre before transitioning to Brazilian Jiu-Jitsu and joining the Mad Hatters.
Drawing from years of experience in combat sports, he's developed a teaching style that combines precise technique with a no-nonsense, hard-working approach. That’s earned him a reputation as both a respected coach and a tough competitor. His approach is based on functional, pressure-tested combat sports. He believes in training smart, rolling hard, and building an environment where both hobbyists and high-level athletes can thrive.
The coaching team at Gorilla Grapplers reflects the same values. Adam has brought together high-level practitioners who match his work ethic and commitment to quality. From seasoned Black Belts to ex-Professional MMA fighters the Gorilla Grapplers coaching staff is made up of dedicated athletes and mentors who are active in the sport and committed to the growth of their students. All have experience competing and winning at national level, all the coaches bring real, hands-on knowledge to every class, along with a clear focus on helping students reach their potential.
What sets this club apart isn’t just technical depth or a competitive mindset - it’s the ability to break down complex movements, foster resilience, and lead a community where mutual respect and personal growth are paramount. This team-centered approach to coaching creates a dynamic learning environment where knowledge is shared, standards are high, and everyone is held accountable to improve.
MAD HATTERS ASYLUM
Mad Hatters Asylum was founded by Jack “The Mad Hatter” Magee, a well-respected BJJ Black Belt under Roberto “Gordo” Correa, a former pro MMA fighter, and a fierce Gi and No-Gi competitor.

Based in Chichester, the team has grown into one of the UK’s most respected and recognised BJJ and MMA academies, known for producing top-level competitors, dedicated coaches, and a clear team identity: tough, technical, and tightly united.
As Head Coach, Jack is known for his analytical style, uncompromising standards, and a proven track record of developing high-level athletes. His coaching blends technical detail, intense drilling, and real-time application, helping students build true confidence under pressure - not just knowledge, but instinct.
The team at Mad Hatters is tight-knit and competitive, forged through mutual respect, honest feedback, and shared goals. From BJJ and No-Gi to Muay Thai and MMA, the Asylum is built for performance across disciplines.
Jack’s coaching influence now extends far beyond the Chichester mats. He has developed a growing network of affiliated teams, including The Gorilla Grapplers in Portsmouth, Garden Club in Gosport, Legacy JJ in Christchurch and the BJJ Exchange in Brighton.
