An instantly recognizable face to daytime television fans, actor Mark Derwin appeared in several soap operas, usually portraying hard-nosed doctors or detectives. Derwin began a long and fruitful soap career with a short run on "The Young and the Restless" (CBS, 1973- ), followed by a more extensive stay on "Guiding Light" (CBS, 1952-2009), where he became a featured cast member. He left soaps for several years in the 1990s for episodic television, but returned with another high-profile role on "One Life to Live" (ABC, 1968- ). The versatile actor also did a fair share of comedy, including a two-year run as Bonnie Hunt's doctor husband on the experimental sitcom, "Life With Bonnie" (ABC, 2002-04). After two decades on daytime television, Derwin turned to primetime drama, playing the harried father of two troubled teenage girls on "The Secret Life of the American Teenager" (ABC Family, 2008- ). Thanks to the quickly popular series, Derwin found a role that perfectly balanced daytime-style melodrama and dry humor, while opening him up to a whole new audience.
