Conan Silveira’s beginnings in martial arts

Marcus Silveira grew up in Rio de Janeiro, Brazil and had an immediate attraction to martial arts. From a young age Conan as his friends and family called him began training under Carlson Gracie.

UFC Promo

After earning his black belt, Conan Silveira would win the Brazillian National BJJ title. Around the same time, Silveira would compete in some of the early bare knuckle luta livre matches in Rio. Winning his first 3 fights before losing to future UFC champion Maurice Smith.

Conan Silveira would then fight Sakuraba in the UFC twice and then avenge his loss to Maurice Smith in 1999.

Fallout with Carlson Gracie

In the late 90s, Carlson Gracie was busy opening his new school in Chicago. Leaving his school in Rio for months, which forced his students like Conan Silveira to run classes.

This absence upset many of Carlson’s Rio students, especially since they were left to train for the BJJ world championship alone. A sequence of events happened after this and Carlson barred many of his top students from his academy.

American Top Team

Conan Silveira’s teammate Ricardo Liborio would go on to co-found Brazilian Top Team, but it was just for a short stint. This is because while in Florida, Liborio and Silveira were approached by businessman Dan Lambert.

Lambert had an idea to build the premiere MMA academy in the world. Taking the idea that helped create Brazilian Top Team and bringing it to the US.

What he, Liborio, and Silveira would create would become known as American Top Team. At this gym, Conan Silveira would be the head coach and be in charge of overseeing the fighter’s camps.

Since 2001, Conan Silveira has been the head coach of ATT and it is the most successful MMA gym. Over 12 world MMA champions and numerous top fighters in the last 20 years have called ATT home. This has all happened with Silveira at the helm as head coach of the gym.
