Hi. My name is Marianna. I am an actor based in New York City. I received my M.F.A. from the Juilliard School Drama Division as a proud member of Group 51. Prior to Juilliard, I earned a B.A. in History from Yale University, where I studied the intersections between American public history, cultural collective memory, and methodologies of storytelling.

NEWS + UPCOMING

I’m playing the title role in Yale Repertory Theatre’s upcoming production of HEDDA GABLER, directed by James Bundy.

Performances run November 28 - December 20. For tickets and more information, see: https://yalerep.org/productions/hedda-gabler-11/

I recently performed the one-person play VANYA as Andrew Scott’s understudy during its NYC run off-Broadway at the Lucille Lortel Theatre (adapted from Anton Chekhov’s Uncle Vanya by Simon Stephens, directed by Sam Yates). VANYA played its final performance on May 11th, 2025.
