## Bio

Simpson Go grew up in Las Vegas, Nevada. He trained wrestling in high school for a short while, but it was in Brazilian Jiu Jitsu that he found a sport that was more adapted to his nature. He started Jiu Jitsu when he was 15 years old, after finding that a BJJ school was running not far from where he lived. There he met (and was taught) by Nova Uniao’s John Lewis and it was also there that Sim was introduced to Marc Laimon who was an instructor there.

Shortly after Sim Go received his BJJ blue belt from John Lewis, Marc Laimon opened his own academy, Cobra Kai and Sim moved with Marc. Though Sim Go was not much of a presence, strength wise, he did possess flexibility and a keen eye for detail, this attention to detail made him into one of the top grapplers in the country in a short period of time and also transformed Sim Go into a top grappling assistant coach at the Cobra Kai academy.

At Cobra Kai Sim also had the opportunity to train with Deep Half Guard guru,  Jeff Glover . Sim Go received his black belt in November 2006 from the hands of Marc Laimon and in time Go became the main Jiu Jitsu coach at the Cobra Kai gym, helping raise the game of competitors such as Chris Holdsworth.
