Career
He has also worked as an East Coast emergency medical technician and firefighter
Saint John has been practicing martial arts since he was five years old and holds a second-degree black belt in Tae Kwon Do, a first-degree black belt in Judo, and he also practices Kenpo. His stage name came as his management team at Pat O"Brien Management Talents thought Jason Geiger was not a strong name, with the actor coming up with "Saint John" himself, and Austin being suggested by the managers inspired by Steve Austin, from The Six Million Dollar Manitoba Saint John"s first major role in acting was in 1993, when he starred as Jason Lee Scott, the Red Power Ranger, in Saban Entertainment"s Mighty Morphin Power Rangers.
Mighty Morphin Power Rangers was an instant success and quickly became one of the highest-rated children"s television programs ever.
However, Austin left the series mid-way through the second season and was replaced as the Red Ranger on the show by Steve Cardenas, who also played the role of the Red Ranger in the first Power Rangers movie instead of Saint John. Saint John later returned to the franchise as the Gold Ranger in Power Rangers: Zeo and as a guest star in the second Power Rangers movie, along with his former castmate Amy Jo Johnson (Kimberly Hart, the original Pink Power Ranger).
Saint John"s last Power Rangers appearance was in the tenth anniversary special "Forever Red," where he joined nine other Red Ranger actors. He once again played the original Red Ranger and was reunited with his former cast mate Jason David Frank (Tommy Oliver, the franchise"s longest-serving Power Ranger).
Saint John was also one of the guest speakers who appeared at the 2007 Power Morphicon convention held in Los Angeles, which celebrated the 15th anniversary of the Power Rangers franchise.
After several years of service overseas Saint John began making convention appearances in 2014 including a return to Power Morphicon. Saint John will return to the acting world in a upcoming post-apocalyptic thriller called Survival"s End.
