Dermot Mulroney

Mulroney was born in Alexandria, Virginia, on Halloween Day in 1963. His father, Michael Mulroney, from Elkader, Iowa, was a law professor at Villanova University School of Law beginning in the 1990s, prior to which he had a private practice in tax law for thirty years in Washington, D.C. His mother, Ellen, originally from Manchester, Iowa, was a regional theater actress. Mulroney is of Irish and German descent, and is the middle child among five siblings. He has two older brothers, Conor and Sean; a younger brother, Kieran Mulroney, who is an actor and screenwriter; and a younger sister, Moira. Mulroney attended Matthew Maury Elementary School and played cello in school and city youth orchestras, as well as acted in children's community theater. He finished 9th and 10th grades at George Washington High School, before attending T. C. Williams High School (class of 1981) in Alexandria, Virginia. During his sophomore year in high school, he attended the Interlochen Arts Camp as a cellist. Beginning at age 18, Mulroney studied communications at Northwestern University in Evanston, Illinois, where he was a member of the Phi Gamma Delta fraternity, and graduated in 1985. Mulroney has a scar on his upper lip from a childhood accident, about which he explained, "I was 3½ and I was carrying a dish for our pet rabbits. And I tripped and it broke, and I fell on it."
