Gareth Dummer

Gareth Dummer's path into Brazilian Jiu-Jitsu began with a defining competitive encounter — a submission loss to Pedro Bessa at a tournament that would prove to be one of the most consequential moments of his life. Rather than stepping away from the experience, Dummer sought out Bessa as a mentor, forging a lasting student-instructor relationship that would shape his entire trajectory in the sport.

Bessa brings considerable depth to his coaching, having trained under Eduardo Telles, Terere, and Careca — a lineage that reflects both technical diversity and deep roots within Brazilian grappling culture. That connection gave Dummer access to a rich technical foundation and a direct line to some of the sport's most innovative practitioners.

Dummer's dedication to his craft has been sustained and deliberate. He earned his black belt under Bessa and continued developing his skills to the level of 2nd Degree Black Belt. His journey stands as a compelling illustration of how a single moment on the competition mat can redirect the entire course of a practitioner's life — turning defeat into the beginning of a lifelong commitment to the art.

In 2009, Gareth Dummer and Lee Jones co-founded Tatami Fightwear in Wales, channeling their passion for Brazilian Jiu-Jitsu into a commercial venture that would grow far beyond its regional origins. Built around the needs of practitioners who understood the demands of quality grappling equipment, Tatami quickly established a reputation for producing reliable, well-crafted gear.

The brand's growth was rapid and tangible. By 2014, Tatami Fightwear had been recognized as one of Wales' fastest-growing businesses — a milestone that reflected both shrewd entrepreneurship and the broader global surge in BJJ's popularity during that period. As the sport expanded its reach across Europe and beyond, Tatami was well-positioned to serve an increasingly international customer base.

Tatami's rise helped put Welsh BJJ on the global map, demonstrating that world-class grappling brands could emerge from outside the traditional hubs of Brazil, the United States, and Japan. Through athlete sponsorships and event partnerships, the company became a significant force in the global BJJ gear market, reinforcing the growing ecosystem around professional grappling.

In 2015, Gareth Dummer joined forces with Matthew Benyon, Ben Tong, and Lee Jones to co-found Polaris Pro Grappling, an invitational event conceived to showcase submission grappling at the highest level. Benyon and Tong brought experience and connections from the Scramble brand, while Dummer and Jones contributed the infrastructure and credibility built through Tatami Fightwear. Together, the four founders created a promotion designed to treat grappling as a legitimate, broadcast-worthy sport.

Format and Philosophy

Polaris was built around a commitment to high-profile matchmaking and professional presentation. The promotion introduced a judging format to its events, providing a structured framework for deciding outcomes beyond submission — a deliberate choice that added strategic depth to the viewing experience and gave athletes clarity on how their performances would be assessed. This approach positioned Polaris as a thoughtful alternative to purely submission-only formats, broadening its appeal to both casual viewers and dedicated fans.

Impact on Professional Grappling

Polaris has grown into one of the most prominent grappling invitationals in the world, featuring elite competitors across both gi and no-gi formats. The event has provided a meaningful platform for professional grapplers at various stages of their careers, contributing to the broader legitimization of submission grappling as a spectator sport. Dummer's role in building Polaris represents one of his most significant contributions to the sport, extending his influence well beyond the mats and into the infrastructure of professional grappling.

Gareth Dummer's commitment to Brazilian Jiu-Jitsu extends into the communities where the sport can have its most meaningful impact. In Port Talbot, Wales, Dummer has been involved in grassroots BJJ outreach, teaching grappling to children in underprivileged areas of the town. This work reflects a deliberate effort to use martial arts as a vehicle for youth engagement and personal development, bringing the lessons of the mat to young people who might not otherwise have access to them.

This community-oriented dimension of Dummer's involvement in BJJ reveals the fuller picture of his contribution to the sport. Beyond building global brands and producing elite grappling events, he has invested time and energy at the local level — using jiu-jitsu as a tool for positive social impact. His efforts in Port Talbot serve as a reminder that the reach of BJJ, and of those who dedicate themselves to it, can extend far beyond competition results and commercial success.
