Actress Helen Greenberg first began appearing on screen in 1993. That year, she was in three different roles. She appeared in the sitcoms "Love & War" and "Down the Shore", as well as in her first movie role in the sci-fi thriller "Ghost in the Machine". She continued from there to land on many of the TV staples of the day. She could be seen, for example, on the critically-lauded comedy "Dream On" in 1994, the quirky David E. Kelley drama "Picket Fences" in 1995, and the sitcom "Grace Under Fire" in 1996. She had her only movie role to date in 1995, when she had a small part playing a flower seller in the family-fantasy "A Little Princess". In 2000, she first appeared on the sitcom "Dharma & Greg" as a character named Carol. Later that year however, she returned to the show as part of the regular cast, playing Marcie, Dharma's neighbor, and played the character, which is still her best known, in 18 episodes until the show's finale in 2002. She has since appeared in guest roles on the sitcom "Two and a Half Men" in 2005 and the crime drama "Law & Order: Criminal Intent" in 2009. She has also appeared in the shorts "As Seen on TV" in 2005, as well as in the TV pilot "Molly Marcy" in 2007.
