Mendes demonstrated an exceptional aptitude for Jiu-Jitsu from the outset, earning a level of trust from his coaches that placed him on an accelerated path. At just 15 — still a yellow belt — he began assisting Alvaro Mansor with classes, an unusually early transition into coaching that reflected both his technical maturity and his natural leadership instincts. By blue belt at age 17, Mendes had been formally integrated into Kioto's instructor roster, working alongside the very coaches who had trained him.
Competitive Dominance at the State Level
His competitive record during this period reinforced his standing on the mats. Mendes claimed the Rio de Janeiro State Championship in 2002, 2003, and 2004 — three consecutive victories that established him as one of the region's standout competitors of his generation. This run of success culminated in December 2004, when Alvaro Mansor and Francisco Mansor promoted him to black belt, formally recognizing his technical depth and his enduring contribution to the academy.
