Marcus Ribeiro Biography

Marcus Vinicius Ribeiro was born on November 17, 1996, in Mogi das Cruzes. a city located near São Paulo, Brazil.

For Ribeiro, the idea of training jiu-jitsu sparked from listening to his school friends, who trained, talk about their experiences in this sport/martial art. Marcus was 13 to 14 years of age and became very curious about grappling, starting his first-class sometime in 2010.

Luciano Marcos was Ribeiro’s very first coach in Marcus’ home town of Mogi das Cruzes. He remained under Luciano’s tuition for 2 years, earning his blue belt there before joining the Alliance Academy where he met Rodolfo Ionta.

At Alliance, and although Ionta was a crucial part in Ribeiro’s development as an athlete, it was once Marcus started spending more time at the team’s affiliate gym in Mooca that Marcus Vinicius’ talent truly started shining through at the international stage. Alliance Mooca is widely recognized as one of the top grappling schools in the world during this time period, much due to the outstanding work being done by coaches Luciano Nucci, Juan Kamezawa, and Rodrigo Siqueira.

At Alliance – Mooca, Ribeiro had the chance to work with an elite level squad, around athletes such as Dimitrius Souza and Guilherme Augusto, who were of great value in Marcus’ development, whose competition record skyrocketed as a brown belt, a time when Marcus Ribeiro earned medals in all 4 of the main IBJJF tournaments, European Open, Pan Championship, Brazilian Nationals and World Championship.

Marcus Ribeiro’s outstanding performances on the mats would earn him his black belt promotion on June 10, 2019, a ceremony led by Luciano Nucci and Alliance’s team leader Fabio Gurgel.
