She was named Miss Rheingold in 1964, the last person to hold that title, and modeled in TV commercials. Her film debut came in "The Nutty Professor" (1963), and she gained further recognition at the 1967 Cannes Film Festival, where she was spotted by producer Harry Alan Towers and cast in the film "Eve".

Celeste Yarnall is perhaps best known for her role as Yeoman Martha Landon in the "Star Trek: The Original Series" episode "The Apple" (1967). She also appeared in "Live a Little, Love a Little" (1968) opposite Elvis Presley, where she famously prompted him to sing "A Little Less Conversation".

Her career included roles in "Beast of Blood" (1971), where she was a "scream queen" terrorized by a headless monster, and "The Velvet Vampire" (1971), where she played a vampire seductress.

In her later years, she transitioned to commercial real estate, founding Celeste Yarnall & Associates, which became one of Los Angeles' top office real-estate firms.

She also authored two best-selling books on holistic pet care, "Natural Cat Care" and "Natural Dog Care," and earned a Ph.D. in nutrition in 1998. Celeste Yarnall passed away on October 7, 2018, at the age of 74, leaving behind a legacy of beauty, talent, and versatility.
