Sherry Lea Stringfield (born June 24, 1967) is an American actress. She is best known for playing the role of Dr. Susan Lewis on the medical television drama ER; a role for which she has received three Emmy Award nominations. Stringfield was one of ER's original cast, but she quit the show during its third season, despite being contractually tied to appear in five. She reprised the role in 2001, but quit once again in 2005.
Away from ER she has acted mainly on television, but she has also played various parts in films. Stringfield has famously left several major roles on successful television programs at the height of their popularity, which has led to her being nicknamed "The Goodbye Girl" in Hollywood.
The eldest of three children, Stringfield was born in Colorado Springs. Her family briefly relocated to Albuquerque, New Mexico, before settling in Spring, Texas, a sister community of Klein, Texas, where Stringfield grew up.
