Katie Finneran's life began in Miami, Florida, where she spent her early years before embarking on a journey to make a name for herself in the entertainment industry. Despite not completing her conservatory training, she decided to leave college to pursue her dreams. Finneran quickly gained recognition in the world of theater, film, and television, appearing in notable productions such as You've Got Mail, Liberty Heights, and Night of the Living Dead.
Her television work includes memorable appearances on Frasier, Oz, and Sex and the City. However, it is her work on stage that has been her greatest achievement. Finneran has had the opportunity to work in regional theaters, including Bay Street and Williamstown Theatre Festival, where she starred alongside Kate Burton in a production of "Hedda Gabler". She has also appeared in "The Smell of the Kill" at the Berkshire Theatre Festival.
In addition to her regional theater work, Finneran has had an impressive list of off-Broadway credits, including "Arms and the Man", "Edith Stein", "Bosoms and Neglect", "You Never Can Tell", "A Fair Country", and Encore's "Lil' Abner".

Finneran's breakout role came when she played Brooke Ashton in Michael Frayn's farce "Noises Off!", earning her critical acclaim and a 2002 Drama Desk and Tony Award for her portrayal. Her success in the show led to her departure on July 14, 2002, as she began working on the CBS sitcom Bram and Alice in 2002.
