Rob started in stand-up comedy at Richard M. Dixon's White House Inn, a talent showcase club on New York’s Long Island run by the presidential look-alike. In the early years, Rob supported himself by day as an elevator operator and telephone salesman for radio advertising. It was at Dixon's club where Rob met a 17-year-old Eddie Murphy, and the two became fast friends, forming two-thirds of the improvisational trio The Identical Triplets.     

When the trio broke up shortly after Eddie's debut on Saturday Night Live, Rob went on as a solo act and became a headliner in comedy clubs and colleges across the country, including shows at the Sands Hotel and Casino in Las Vegas, Atlantic City’s Tropicana and Hilton Hotels, Mohegan Sun and Foxwoods Resort and Casinos. As a Stand-Up, appeared on the MTV Half Hour Comedy Hour, Standup Spotlight on VH1 and on Late Night with David Letterman and Conan O’Brien.

Rob made his Broadway debut as author and star of More to Love. His Broadway Credits also include Amos Hart in Chicago, Mr. Mushnik in the 2003 revival of Little Shop of Horrors, Herman in the 2005 revival of Sweet Charity with Christina Applegate Speed, the poker playing crony of Oscar and Felix, in the revival of Neil Simon’s The Odd Couple with Nathan Lane and Matthew Broderick, and the dual roles of Twimble/Womper in the 2008 Revival of ‘How to Succeed in Business’ with Daniel Radcliffe and Nick Jonas. 

His other stage appearances include Golden Boy and Pardon My English for City Center’s Encores!. In 2001 Rob received a Drama Desk award for his role as ‘Marcus’ in Rob Ackerman’s Off-Broadway Production of 'Tabletop' and revisited the character in a film short titled ‘Standing By’ based on the play.

Rob’s television credits include Recurring Guest Star roles as attorney Milton Schoenfeld on Law & Order, Special Victims Unit, Bernie Bucovitz on ‘The Good Wife’ and, most recently, a 5 episode Story Arc as Captain Bill Dwyer.  He was the voice of ‘Marty the Dog’ in the Award Winning, animated ‘Kenny The Shark’ series for NBC and the Discovery Channel.

He wrote and starred in the Public Television special, Rob Bartlett's Not For Profit T.V. Special, produced by CPTV, which was nominated for five Emmy Awards and won for Best Writing and Best Entertainment Program.

Rob is very proud to have been voted one of the "Top Ten Worst" wrestling announcers in history for his short-lived stint as the original color commentator on the WWF Monday Night Raw program on USA Network.
