Goodwin, like Kirstie Alley, was born in Wichita, Kansas. Unlike Alley, however, who had begun her career with proceeds from game-show winnings, Laurel began her career as a child model. She majored in drama at San Francisco State University, with her break coming when she was selected to star opposite Elvis Presley in the 1962 film Girls! Girls! Girls!. During the 1960s, Goodwin made three more feature films and performed in a handful of television guest star roles. Tired of "pounding the pavement," she abandoned acting in 1971 and went into the health care business. Although she had attended a few Elvis conventions over the years, it was not until 2005 that she attended her first Trek convention, along with Peter Duryea.
For many years, she lived with her husband, business executive Walter Wood, in New York. Together they produced several films, most notably – in partnership with Hugh Wilson and others – the Burt Reynolds film, Stroker Ace, which Hal Needham directed and in which Warren Stevens was featured. In the mid 1990s, she and her husband moved to Palm Springs, where Goodwin pursued a career in home nursing. In 2009, her husband became seriously ill and she nursed him until his death. As of August 2016, she still lives in Palm Springs.
