Josei Heishi Black Belt Ambassadors

Josei Heishi BJJ Black Belt Ambassadors Karen Miller Peterson

Professor Karen Miller Peterson

Karen started Brazilian Jiu Jitsu in 2004 , looking for a new way to exercise that could be useful for self defense too. BJJ was exactly that and she was hooked. She competed for the first time in 2005 and despite losing that first competition, she loved the unique journey of preparing for it and went on to compete more, winning multiple international titles.

In 2007, she started a Women Only BJJ and self-defense program. Additionally, she taught co­ed and mixed level classes for her instructor. She still gets so excited to watch students change through BJJ through weight loss, improved skill, belt promotions, competitions, or in the confidence they gain from doing Jiu Jitsu. In 2010 she moved to New York City to train with Josh Griffiths at Clockwork Jiu Jitsu, receiving her black belt a year later. In addition to teaching classes, Karen also offers private teaching for those students who enjoy one-on-one lessons.
