The acting bug bit Dianne Kay early in her career, when at the age of thirteen, she joined a community theatre group in her home town of Phoenix, Arizona. Her acting coach introduced her to an agent and Dianne's first job was to sell honey diet food at Skaggs, the local drugstore. The catch was, she had to dress as a bumblebee complete with antennas and a stinger. Always the trooper, Dianne spread her wings as a method actress and perfected the "buzz" of the sales pitch. Unfortunately, the job was short lived due to an irate customer who suffered from Apiphobia (fear of bees) and proceeded to chase Dianne out of the store with a flyswatter.

This incident did not detour Dianne from following her dream. Dianne remained steadfast and continued to study acting. She was cast in national television commercials while studying drama and communications at The University of Arizona. After graduating in 1976, Dianne drove to Hollywood in her grandmother’s 1964 Chevy. Upon arrival, Dianne signed with the famous Nina Blanchard agency and two days later, Dianne was sent on her first television audition. She landed a guest starring role on "The Kids from C.A.P.E.R."

Dianne continued working in episodic television playing many different roles including a kidnapped hostage on “Starsky and Hutch.” In 1977, Dianne was cast as Nancy Bradford on the hit television series, “Eight is Enough,” which had a five year run.

A highlight of Dianne's career was playing the part of Betty Douglas, a USO dancer, in Steven Spielberg’s film, “1941.”

Dianne took a hiatus from acting to get married and raise a family. Currently, she resides in Los Angeles and is developing a comedy series called "Seconds."
