Parrish played the wholesome civil libertarian Jocelyn Jordan in the 1962 political psycho-drama The Manchurian Candidate, which also had work for her future fellow TOS guest actors Reggie Nalder, Whit Bissell and James Gregory. She starred alongside Robert Easton in Bill Rebane's 1975 B-movie The Giant Spider Invasion.
On television, she guest starred on Batman twice, first in 1966 alongside Charles Picerni and directed by Robert Butler, then in 1967, with Elisha Cook, Jr.. She also appeared in two episodes of The Wild Wild West, once with Michael Dunn, Bill Catching, Troy Melton and Hal Needham, and once alongside William Windom and Bob Herron, directed by Robert Sparr.
She married Richard Bach, author of Jonathan Livingston Seagull in 1977. She has amassed about seventy-five television and movie credits (including a role in the film adaptation of Bach's novel). She and her (now ex-)husband lived in the San Juan Islands of Washington State.
