Jiu-Jitsu Collective is an independent jiu-jitsu academy in Oslo, with gi and no-gi classes from your first session to black belt.
Every class is planned and taught by head coach Mikolaj Mazur, a black belt under Unity Jiu-Jitsu and an IBJJF European and Pan American medallist. Training is structured and taught with close attention to detail.
Beginners are guided carefully from the start, and experienced students work on the details that move their game forward.
