Following her work as a film publicist, she became the director of media relations at HBO. Then, in 2004 Robertson returned to the PR world and joined the Dart Group, a start-up public relations firm that grew into PR company 42West. She helped represent clients such as Tom Hanks, Noah Baumbach and Jonathan Demme. She also managed campaigns for movies like Mel Brooks’s “The Producers,” “The Interpreter” starring Nicole Kidman and “The Squid and the Whale” with Jessie Eisenberg.

After moving to the San Francisco Bay Area, she worked as director of communications for the Walt Disney Family Museum.
