She made her acting debut appearing in a 1961 episode of Alfred Hitchcock Presents, Bang! You're Dead, alongside Billy Mumy. She went to star as Lorelei in the movie, Beach Blanket Bingo and made guest appearances in numerous TV shows.

Her career breakthrough came in Lost in Space, where she played one of the daughters of Professor John and Maureen Robinson from 1965 to 1968. Her mature role allowed adult form-fitting fashions and hairstyles as shown in publicity photos of the TV series. She says about 2018 revival of Lost In Space in Netflix, 

“It sounds interesting, and they’re making 10 episodes for the first season. I might be interested in a part of some sort, but not necessarily as Judy Robinson. I hope fans of the old show won’t be disappointed. They have such great love for the original and are really part of the ‘Lost in Space’ family.”
