Marcia Strassman (born April 28, 1948 in New York City) is an American actress who is best known for her role as Julie Kotter in the TV sitcom Welcome Back, Kotter and the 1989 feature film, Honey, I Shrunk the Kids and its sequels. Prior to that she had appeared in an episode of The Patty Duke Show. This was followed by the recurring role as nurse Margie Cutler in the earliest episodes of M*A*S*H. A regular character who was also shown in the opening titles sequence when the series began, she disappeared from the show and was cut from the title sequence after appearing in just six episodes.
Ms. Strassman is frequently mistaken for WKRP in Cincinnati cast member Jan Smithers, to whom she bears a close resemblance.
