American stage, film, and television actress, Kristen Johnston has an estimated net worth of $13 million.
She is best known as the husky-voiced, no-nonsense Lt. Sally Solomon on the hit NBC fantasy sitcom 3rd Rock from the Sun (1996-2001) — a role she played, opposite heavyweights John Lithgow and Jane Curtin, for the entire six-year run of the series — fair-haired Kristen Johnson parlayed her success from that effort into a handful of A-list cinematic releases, beginning in 1999.
Born January 20, 1967, in Washington, D.C., Johnston moved with her family to Wisconsin and attended high school in suburban Milwaukee. She is the daughter of a real estate agent and a Republican state senator from Wisconsin.
