The coaching team

Meet Your Instructors

You learn from coaches who genuinely care about your progress on and off the mats. Our team brings together championship-level Brazilian Jiu-Jitsu, women's and kids instruction, strength coaching, and Muay Thai — all under one roof in Rockland, Maine. Flow BJJ is proud to be part of the Tom DeBlass Association, a worldwide network of 60+ schools tracing its lineage back through Renzo Gracie and Ricardo Almeida to the founders of the art.
