Grahn also has had several roles on daytime dramas. Her first television role was as Beverly Wilkes, Marco Dane's secretary on ABC's One Life to Live from 1978 to 1982. In 1985, she was cast as headstrong lawyer Julia Wainwright Capwell, on the now-defunct soap opera Santa Barbara. Julia was a departure from the traditional "damsel in distress" or vixen roles; she was an intelligent, uncompromising woman. Julia was paired with Mason Capwell, and the two had a Tracy/Hepburn-esque romance. Offscreen, Grahn was briefly involved with Mason's portrayer, actor Lane Davies; conflict over their storylines eventually led to Davies' departure from the series.  Grahn's performance garnered her a Daytime Emmy Award for Best Supporting Actress in 1989, an award which she shares with All My Children actress Debbi Morgan. She portrayed the role of Julia until the show's cancellation in 1993.
