Marcia A. Strassman (born April 28, 1948) is an American actress best-known for her roles as Julie Kotter in the TV sitcom Welcome Back, Kotter and Diane Szalinski in the 1989 feature film Honey, I Shrunk the Kids, its first sequel Honey, I Blew Up the Kid and the 3-D film spin-off Honey, I Shrunk the Audience! which was shown at several Disney theme parks through mid-2010.
Strassman was born in New York City. Among her earliest acting credits was an appearance in an episode of The Patty Duke Show. In 1967, she became a recording artist for UNI Records. Her debut single, "The Flower Children", was a top 40 hit in many West Coast U.S. markets, most notably hitting #4 in San Diego and #2 in San Francisco; the track also hit #2 in Vancouver, Canada (CKLG 730 AM or CFUN 1410 AM in July 1967). However, the single failed to break out nationally in either country, stalling at #103 (U.S.). Strassman's followup release, "The Groovy World of Jack & Jill," charted in Denver but virtually nowhere else. A third single, 1968's "Star Gazer" (produced by Kim Fowley), failed to chart anywhere and brought Strassman's brief recording career to a close.
Returning to acting after a gap of a few years, Strassman landed the recurring role of nurse Margie Cutler in the earliest episodes of M*A*S*H. She appeared in six episodes.
