Mark's journey began in Jersey City, where he was born, and continued in New York, where he was raised. He graduated from SUNY Stony Brook, and during his studies, he spent a year at the University of Manchester in England, where he traveled extensively throughout Europe and the Middle East with just a backpack, which sparked his curiosity about what makes people so different yet so similar, a driving force behind his acting career.
Returning to New York, Mark worked undercover for the NYPD to earn enough money to move to Los Angeles, and shortly after, he landed his Screen Actors Guild card by playing a junkyard night watchman in the final episode of the TV series, The FBI. He then embarked on a long-term study period with renowned acting coach Jeff Corey, substituting cleaning duties for tuition.
Producer Aaron Spelling discovered Mark in a clothing commercial and cast him in several popular TV shows of the time. He went on to secure guest roles at other studios, as well as recurring roles in Matt Houston, Paper Dolls, and Babylon 5. Mark also made appearances in various soaps, including extended roles in Santa Barbara and Days Of Our Lives.
He performed lead roles in network pilots for Goldie And The Bears, Murphy's Law, and The Nightingales, but none of these projects were picked up as series. Mark later worked on MTV's first soap format, Spyder Games, and starred in the 90-episode Fox series, Forever.
In addition to his work in television, Mark has appeared in numerous feature films, including low-budget productions like Burnout and Supervan, a cult classic in which he drove a legendary solar-powered van created by George Barris. He has also starred in bigger budget films, such as Ivan Reitman's Ghostbusters II, Blake Edwards' Son Of The Pink Panther, and alongside John Houston in his final film appearance, A Minor Miracle.
From his early days at Second City to his extensive work in film and television, Mark has relished the challenge of bringing characters to life, hoping that they will reflect a bit of himself and the audience as they navigate their own journeys. As he admits, "my greatest reward is sharing the ride with laughter, tears, joy, and revelation."
