Megan Gallagher wanted to act from the time she was five years old. She later took drama lessons when she was in high school. She moved to New York to attend the Juilliard and appeared in the Broadway cast of "A Few Good Men" where she won two theater awards (Theatre World and Outer Critics Circle Award for outstanding debut) for her Broadway performance in "A Few Good Men". After graduating from Juilliard with a bachelor's degree, she began to work with John Houseman's Acting Company and soon had screen roles in TV movies and miniseries, but was so discouraged trying to make it in L.A. that she nearly gave up to go to law school. Then she won the "Hill Street Blues" (1981) role, which developed from a guest star to a regular role. The rest is history.

Megan is the second youngest of six kids. She has three brothers and two sisters.

She has a basset hound named Henry and two cats.

She is known to stay away from red meat.

Before appearing in movies, she appeared in an off-off-Broadway production of the August Strindberg play, "Miss Julie", in the basement of a church on East 90th Street in New York City. She was a lovely fresh-faced 23 year old at the time (c. 1983). There could not have been more than 20 people in the audience, but they were all captivated by her. Her later success was too long delayed but totally expected.

Sister-in-law of Kevin Yagher and Catherine Hicks.
