Seth Peterson was born in Harlem, NY and bounced back-and-forth between Brooklyn and Los Angeles in his early years. His father was a high school mathematics teacher, and before becoming a computer technician, his mother was an actress who performed at the Colony Theatre in Los Angeles, California. Peterson enjoyed his younger days at the theater so much that he returned to perform there after high school.   For 10 years, Seth Peterson studied a variety of acting methods, appeared in local equity-waiver theater and worked part-time jobs to support himself. "I just kept plugging away," he recalls.   This practical approach landed Peterson guest-star roles in such series as "Arsenio," "Clueless," "Relativity," and "Beverly Hills, 90210" early in his career. Peterson later went on to be a series regular on NBC's "Providence" and a recurring role as "Nate" in the popular USA Network series "Burn Notice." His feature-film credits include "Godzilla," "Can't Hardly Wait," the award-winning independent film "Hate Crime," and the feature film "Sedona."
