O'Donnell has shared her creative duties with co-artistic directors Stephen Adly Guirgis and Yul Vázquez for the past several years. It has been a custom of the 21-year-old theatre company to appoint several individuals to share leadership roles.

"Stephen, Mimi and Yul successfully transitioned from for our long-time artistic directors, Philip Seymour Hoffman and John Ortiz," board chairman Jeffrey A. Horwitz said in a statement. "During the course of these past four seasons, the company has grown in profound and lasting ways. We finally have a theatre to call our own, we made our Tony-nominated Broadway debut, we expanded our programming both on-stage and off, and Stephen, Mimi and Yul helped build a strong foundation that will sustain our company for years to come. Today, we are thrilled to announce that Mimi will continue the work she's done over the past four years, leading our ensemble of passionate artists and implementing her exciting vision for the next chapter in our history. On behalf of the board of directors, we offer our sincerest thanks to Yul and Stephen for their years of invaluable service and look forward to working with Mimi in her new role."

O'Donnell added, "Personally, I'm honored to be able to expand upon the work we've done and am very excited to guide our extraordinary ensemble and vibrant institution into a new period of sustained growth. Labyrinth has been, and always will be, a vital source for New York City audiences to engage with diverse new plays, and I look forward to carrying on that important tradition in the years to come."

O'Donnell also directed the world premiere of Thinner Than Water and was nominated for a Tony Award as a producer of the Broadway debut of The Motherf**ker with the Hat. She has designed costumes for The Motherf**ker With The Hat, Jack Goes Boating, The Little Flower of East Orange, The Last Days of Judas Iscariot, and the Off-Broadway, West End, and Donmar Warehouse productions of Jesus Hopped The A Train.
