Geoff began as a stuntman working in the Universal Studios Hollywood Tour, where he worked in the "Wild West Stunt Show", "The Adventures of Conan", and "The Miami Vice Action Spectacular." Using that as a springboard, Geoff performed almost all of his own stunts as an actor, from going through glass windows, to highfalls, to car chases, to doing all of his own extensive fighting with stars such as Steven Seagal, Chuck Norris, and Mark Dacascos.

As a playwright, Geoff has had five original plays produced in Los Angeles. He directed four of them, and starred in all five.

After being severely injured on a TV movie in 2012, which turned into a workers comp lawsuit, Geoff "semi-retired" from acting, and opened his own fitness/martial arts studio in the suburbs of Houston, Texas, while loosely keeping his foot in the door in Hollywood. In November 2016, he returned to Los Angeles t pick up again, after a much needed break.
