Stage director Daniel Sullivan began his professional career as an actor at San Francisco's Actor's Workshop, worked as both an actor and director with the Lincoln Center Repertory Company in the 60s and 70s and served as assistant director of the original Broadway production of "Hair". After two years as Resident Director of the Seattle Repertory Company, he assumed the reins as its Artistic Director in 1981, serving until 1997. Sullivan has forged working relationships with several prominent contemporary American playwrights, notably Herb Gardner (the Tony-winning "I'm Not Rappaport" and "Conversation With My Father"), Wendy Wasserstein (the Pulitzer-winning "The Heidi Chronicles", "The Sisters Rosensweig" and "An American Daughter") and Jon Robin Baitz ("The Substance of Fire" and "A Fair Country"), many of them originating at Seattle Rep. Sullivan made his feature directorial debut with the screen adaptation of Baitz's "The Substance of Fire" (1996), which successfully opened up the action of the play. In 2000, he enjoyed another stage hit with "Proof", a comedy-drama about a young female mathematician that offered a tour de force for actress Mary-Louise Parker. For his work, Sullivan finally earned a well-deserved Tony Award.
