Bradley is known for his role as Sean Davidson in American Ninja 3: Blood Hunt and American Ninja 4: The Annihilation. He also stars in a separate film titled, American Ninja V, as Joe Kastle, which is not technically a sequel to the previous American Ninja films, but a different movie altogether.^[3] Previous to making films, Bradley worked as a car salesman on Wilshire Boulevard. He attended the screening of American Ninja 3: Blood Hunt in Los Angeles, and director Cedric Sundstrom claimed that he in Bradley found a good balance between vulnerability and physical aspects.^[2] According to Sundstrom, Bradley always resented the fact that his character got rescued by Michael Dudikoff's character in the film American Ninja 4: The Annihilation.^[2]

Bradley is trained in Shotokan Karate (black belt), Taekwondo (4th Dan black belt), Kung Fu, Aikido and weapons.^[2]
