Beth Williams (b. Chicago, 19 October 1961), Executive Producer of the 2010 revival of Promises, Promises on Broadway, is the COO and Head of Production for Key Brand Entertainment, parent company of the producer corporation Broadway Across America. She began her 25-year Broadway career as Beth Fremgen, replacing the Assistant Conductor for Dreamgirls in 1987. She also served as Company Manager for that show, as she did two years later for Dangerous Games, a resounding flop. She was the rehearsal pianist for Miss Saigon (1991) and Sunset Boulevard (1994), and Assistant Conductor for Les Misérables from 1992 to 1997.
In 1999, under her married name, Beth Williams took on her present role as an Executive Producer for Fosse (1999), The Sweet Smell of Success (2002), Grey Gardens (2006), and Promises, Promises (2010).
