Biography
Stan was born in the Romanian city of Constanţa. At age 8, he and his mother moved to Vienna, where she was employed as a pianist. Four years later (age 12), his mother moved with him to Rockland County, New York after she married the headmaster of an American private school.

During his years at the Rockland Country Day School, he starred in productions such as Harvey, Cyrano de Bergerac, Little Shop of Horrors, Over Here, and West Side Story. He also attended the Stagedoor Manor summer camp where he was introduced to acting and was cast in many camp productions. It was then that he decided to take acting seriously and began to apply for acting programs at several universities.

He was accepted to and attended Rutgers University's Mason Gross School of the Arts. This gave him the opportunity to spend a year abroad studying acting at Shakespeare's Globe Theatre in London, England.
