Over the course of his coaching career, he has promoted tens of black belts, placing him among the most productive instructors in the history of Brazilian BJJ. The depth and consistency of his promotion record speak to a teaching philosophy rooted in patience, technical precision, and long-term athlete development.
Referee and Competitor
Beyond the academy, Muzio has earned recognition as one of the most experienced referees within the CBJJ/IBJJF officiating structure, bringing a practitioner's technical knowledge and a coach's understanding of competitive dynamics to high-level tournament officiating. His presence at major IBJJF events has contributed to the integrity and professionalism of competition environments across the sport.
As a competitor, Muzio performed in the Meio Pesado — Medium Heavyweight (88.3kg) division, earning distinction at both national and international levels. His competitive record includes two Internacional de Masters e Seniors titles (2003 and 2008), three Brazilian National silver medals (2004, 2005, and 2008), a Pan American bronze medal in 2000, and a Brazilian national title at brown belt. Together, his roles as instructor, referee, and competitor reflect a comprehensive and enduring investment in every dimension of Brazilian Jiu-Jitsu's growth and integrity.
