Marina Sirtis was born in London, England, to Greek parents, Despina (Yianniri), a tailor’s assistant, and John Sirtis. Her parents did not want her to become an actress. As soon as Marina completed high school, she secretly applied to the Guildhall School of Music and Drama. After her graduation, she worked in musical theater, repertory, and television. In 1986, she moved to Los Angeles, California, to boost her career.

For six months, she auditioned for roles but was unsuccessful. Before she planned to go back home, she got Counselor Deanna Troi’s role on Star Trek: The Next Generation (1987). After the series ended, she reprised her role for a string of successful Star Trek films: Star Trek: Generations (1994), Star Trek: First Contact (1996), Star Trek: Insurrection (1998), and Star Trek: Nemesis (2002). In 1992, Sirtis married rock guitarist Michael Lamper. She occasionally attends Star Trek conventions so that her loving fans can meet her, and she can meet the fans.
