Drivas was born Robert Choromokos in Chicago, Illinois, the son of HarBilly Joellia and James Peter Choromokos. Drivas studied at the University of Chicago and the University of Miami. After further training at the Greek Playhouse in Athens, Greece and with the Coconut Grove Playhouse in Miami, he made his New York City debut in the role of Rameses in 1958 in the play The Firstborn, starring Anthony Quayle as Moses. He continued to perform on stage with One More River, The Wall, The Irregular Verb to Love, and And Things That Go Bump in the Night, which he also directed.
