Robert started his show business career at the age of six when he was discovered by his manager, Jeff Mitchell, of J. Mitchell Management while walking down the street in Manhattan with his dad. Robert was immediately hired to appear in a Pizza Hut commercial but quickly decided that he really wanted to just be a "regular kid" so he retired from show business to concentrate on school, sports and his friends.

At the age of ten Robert decided he wanted to give show business another shot. He returned to the business and appeared in numerous commercials and the feature film 'The Tic Code' with Gregory Hines before being the cast as Anthony Jr., the son of mob boss Tony Soprano, in the HBO's hit series The Sopranos.

Robert received a Screen Actors Guild award for best ensemble cast for his role in The Sopranos. He won the Hollywood Reporter's Young Star Award for best young actor in a drama TV series, two years in a row (1999 and 2000), for his work in The Sopranos.

Robert appeared with Sigourney Weaver and John Ritter in the 1999 Miramax film, 'Tadpole.' Last year he also appeared in the film 'Daredevil' with Ben Affleck.
