Abby Corrigan was born in 1998 in Charlotte, North Carolina, just five minutes after her identical twin sister, Emma, who was born with Down syndrome. Their father, Mike, is a manager of sign language interpreters and a closet musician, while their mother, Mitzi, is a Casting Director with deep roots in Charlotte's theatre history. The couple was involved with various local theatre companies, including the Charlotte Shakespeare Company, Charlotte Repertory Theatre, and Theatre Charlotte.
Growing up, Abby and Emma spent countless hours in the theatre, watching rehearsals or auditions, which sparked Abby's interest in acting at a very young age. She took classes at the Children's Theatre of Charlotte, auditioned for plays, and also received ballet, dance, and singing lessons. In grade school, Abby co-founded the Treehouse Acting Company with her friend Matt Mitchell, providing opportunities for young artists to take on larger roles. The company produced, directed, and acted in several plays, including the award-winning original teen rock musical Cyber Soul.
Abby attended the Northwest School of the Arts, where she continued to hone her craft both in and out of school. During the summers, she studied acting and voice in Los Angeles. Her stage credits include the Emcee in Cabaret, Daniela in In The Heights, Peter Pan in Peter Pan, Natalie in Next To Normal, and Maureen in Rent. She received the Blumey's Best Actress Award for her performance as Fiona in Shrek The Musical in 2014.
Abby's film and television credits include Headed South For Christmas, A Smile As Big As The Moon, The Ultimate Life, Redneck Roots, Homeland, Rectify, and Banshee. During her college Unified auditions in New York City, she was called to audition for the National Broadway Tour of Fun Home and was thrilled to land the role of Medium Alison. She has been touring the United States since September 2016 and continued to perform through December 2017.
