A native of Portland, Oregon, Harrison started acting as a child in small theaters in the area. However, it wasn’t until a teacher at the Northwest Children’s Theater challenged him to become the best actor he could be that he began taking acting seriously. He was so inspired that he graduated high school early and headed to Los Angeles on his own. Within months of arriving in town, Harrison won the role in Grounded For Life.

Harrison’s other television and movie credits include guest-starring roles in the dramas The O.C. and Law & Order: SVU. He co-starred in the film Orange County, opposite Colin Hanks and Jack Black, and appeared opposite Laura Prepon in Lightning Bug. In addition, he was a regular on the first season of the MTV series Undressed and appeared in MTV’s film Everybody’s Doing It, which addressed sex education.
