Heidi Frantzen is one of the senior female brown belts on the Rogaland mat, training and instructing out of Kampsporthuset Gausel BJJ in Stavanger. Among her training partners she has a reputation as a "walking BJJ encyclopedia" — the kind of room-level credibility that doesn't show up on a medal table but defines who actually shapes a club's technique.
Her recent competition life includes the 2024 ADCC Denmark Open, where she entered multiple divisions — the standard signal of a brown belt willing to take on the harder bracket structures rather than picking a single comfortable bracket.
In a country whose female BJJ population is still smaller than its male, Frantzen is one of the brown belts whose long tenure inside a regional academy quietly makes it a place that other women can show up to and stay. Rogaland's women's programme owes a meaningful piece of itself to that work.
