John Richard Petersen (August 15, 1961 Chicago, Illinois, USA) was born and raised in Schiller Park, Illinois, just outside of Chicago's O'Hare Airport.
After graduating from East Leyden High School John headed west and attended college at the University of Arizona where he was offered a full acting scholarship after his first semester. Tucson, Arizona and it's old west movie studio location "Old Tucson" was a favorite with Michael Landon and John soon found himself on the set of "Little House on the Prairie" and "Father Murphy" in addition to Sidney Poitier's films "Stir Crazy" and "Hanky Panky" as extra and stand in.
As the years passed John grew into an adult and finally started getting cast as "the father" on stage. Emerging from the chorus he took on leads in many local Orange County musical productions along with many dramas. This allowed John the confidence to return to Hollywood as a full fledged adult performer. When not in front of the camera John continues to be involved with theater throughout Southern California.
