She built momentum through theater and bit parts in shows like L.A. Law, where she played a recurring character over six episodes, and films including Ratboy (1986), allowing her to develop a knack for eccentric, memorable supporting turns amid Hollywood’s competitive landscape.

Delano’s breakthrough arrived in the 1990s with her recurring role as the no-nonsense Sergeant Barbara Semanski on Northern Exposure, appearing in 12 episodes and earning praise for injecting dry humor and authority into the quirky Alaskan ensemble.

She also ventured into films like Miracle Mile (1988) and expanded into voice acting, voicing characters in Superman: The Animated Series and Teen Titans, while tackling edgier parts in Jeepers Creepers 2 (2003) and The Wicker Man (2006) as the cultish Sister Beech.
