Marcelo Gomide Oliveira was born on August 21, 1992, in Belo Horizonte, the capital city of the Brazilian state of Minas Gerais.
The concept of sports as a lifestyle was embedded in Marcelo’s routine from very early on in his life, being particularly submerged in five-a-side football (futsal) and judo, a martial art he started at the age of 7.

Although successful in competitive judo, as Marcelo grew into his teens his interest in martial arts died down and he eventually dropped the kimono. 

At the age of 18, after paying close attention to mixed martial arts (MMA), Gomide decided to try a jiu-jitsu class and hopefully acquire some ground fighting skills. Gomide’s first jiu-jitsu coach was one of Minas Gerais’ foremost black belts, Erik Wanderley, the man who reignited in Marcelo the fire to compete, and the man who followed his path from white to black belt.
As a purple belt, Marcelo decided to focus all his spare time to jiu-jitsu, this being one of the most important phases of his career. Later on, Gomide would cross-train with Gracie Barra’s Belo Horizonte headquarters under the guidance of Claudio Caloquinha e Sergio Benini.

After over two years competing in the brown belt division, on June 2019, coach Erik Wanderley promoted Marcelo Gomide to black belt, in a ceremony that took place at the Gracie Barra Mangabeiras Academy, where they both taught.
After Gracie Barra Mangabeiras, they moved to another neighbourhood and founded Gracie Barra Cobre, where Marcelo taught before coming to Australia. Arriving in Sydney, he decided, together with his partners, to create his own team which became Trinity Brazilian Jiu Jitsu.
