Daniel Sørensen began training martial arts in 2001 and, four years later, was one of the founders of Bergen Grappling, the first dedicated BJJ and submission wrestling club in Norway's second city. Before that, Bergen had pieces of grappling distributed across judo and MMA gyms; afterwards, it had a real home.
Two decades later, he is still on the mats there as a black belt and submission wrestling instructor, anchoring the kind of long-form community work that turns a club into an institution. The Bergen Grappling room he helped start has produced black belts, competitors and a steady international seminar programme through the Artemis BJJ Bergen Camp.
Outside the academy he works as an electrical technician, which is to say: he is one of the many Norwegian black belts whose contribution to the sport has been built on top of a full-time non-fighting career.
