Reshetar started his acting career at the age of 10 when he performed as an ensemble member in several productions at Holy Name High School, where he spent four years from 2002-2006. When he wasn’t onstage, he excelled in his studies with the piano/keyboard and guitar and spent time singing with men’s chorus groups while in high school. In sports, he played golf, tennis, and basketball.
