Pedro Marinho is one of the main representatives of the Gracie-Barra Academy in jiu-jitsu's professional circuit, who worked extensively with coaches Ulpiano Malachias, Felipe Pena (Preguiça), and Reinaldo Fernandes. Marinho first made waves in the sport as a purple belt, a time when he beat several top-ranked black belts while competing and winning professional no-gi events such as Elite Grappling and Jitz King.
