A model-turned-actress, Dromm rose to national fame (very briefly) in a 1960s National Airlines TV commercial, in which she played a sexy stewardess and delivered the popular catchphrase "Is this any way to run an airline? You bet it is." The phrase was often parodied and was even referenced in several reviews of the 1967 film Come Spy With Me, in which she starred, which would run along the lines of "Is this any way to make a movie? You bet it isn't".
She was also among many Star Trek alumni to star in the 1966 film The Russians Are Coming, the Russians Are Coming. Her co-stars in this classic war comedy included Brian Keith, Theodore Bikel, Sheldon Collins, Guy Raymond, Don Keefer, Michael J. Pollard, and Paul Lambert.
Dromm was considered to become a regular on Star Trek, however she had to choose between the aforementioned film and the series, from which she chose the former, citing the uncertainty about Star Trek becoming a success. She was replaced by Grace Lee Whitney, playing Yeoman Rand. Robert Justman and Herb Solow claims that Dromm was hired by Gene Roddenberry so he could "score with her", but she insists that she had "no problems" with the famous womanizer.
