Professional wrestling career Early career While writing for a wrestling video game website, Excalibur met Super Dragon online. Through chatting online, the two became friends and it helped spark the beginning of Excalibur's career. After spending a year in college, Excalibur chose to move to California to begin his wrestling career and also get work in his full-time profession, graphic design. He cited having an "in" to Revolution Pro Wrestling as the reason he decided to leave his hometown of Detroit. After moving to California in late 1999, Excalibur spent six months living in Super Dragon's garage, until finally renting a place of his own. Pro Wrestling Guerrilla (2003–2008) Excalibur is one of the six owners of Southern California-based Pro Wrestling Guerrilla (PWG), and is collectively known as one of the "PWG Six", in reference to his partial founding of the company. On PWG's debut show, he defeated Chris Bosh. Soon after, Excalibur became a member of the stable SBS with Super Dragon and Disco Machine. While with SBS, Excalibur and Super Dragon won the company's Tag Team Championship from Quicksilver and Chris Bosh. They became the first team in PWG's history to successfully defend the title, but they eventually lost them to Joey Ryan and Scott Lost.
