Colleen McGuinness is an American producer and screenwriter who has worked on the television shows 30 Rock, About a Boy, and Mercy. After joining 30 Rock in 2011, she shared in its 2013 Emmy nomination for best series as well as in its 2013 and 2014 WGA nominations and 2014 PGA nomination. Together with Game of Thrones executive producer Carolyn Strauss, she is working with HBO to develop a comedy series based on the novel Prep by Curtis Sittenfeld.
According to IMDb, Colleen McGuinness was born in Killeen, Texas on May 21, 1977. McGuinness, who is of Irish and Korean heritage, was raised by her grandparents in Islip, New York. Variety, in a 2004 article calling McGuinness a "tyro scribe," said that McGuinness had been a tennis champion in high school.
McGuinness's early writing credits include story-editor work for prime-time soap opera North Shore and a staff writer position with Alicia Silverstone's Miss Match.
McGuinness was hired by 30 Rock in 2011 and served as producer, co-producer, and writer during the show's final two seasons. She is listed as co-writer (with Jack Burditt) of one of the show's 2012 episodes, "My Whole Life Is Thunder", and as sole writer for another, "St. Patrick's Day".
After 30 Rock stopped production, McGuinness worked as a writer and supervising producer for About A Boy. When Tina Fey started her new production company Little Stranger productions, her company's first sale was an untitled comedy to be written by McGuinness and executive-produced by Fey and by former 30 Rock showrunner Robert Carlock.
