Miller was born and raised in Allentown, Pennsylvania, where she attended William Allen High School. Her father owned a pajama factory while her mother stayed home, and she got her start performing on Broadway—notably playing Amaryllis opposite Dick Van Dyke in a revival of The Music Man.
In 1981, she landed a starring role on the NBC sitcom Gimme a Break!, playing the tomboyish Sam Kanisky alongside Nell Carter. The show ran for six years and made her a recognizable name in TV.
After the series wrapped in 1987, Miller made an interesting pivot: she moved back east and finished her undergrad at NYU as a Phi Beta Kappa graduate, where she'd also been on the women's varsity tennis team and continued performing in regional theater. She then went on to law school at Fordham, graduating four years later. She's licensed to practice law in New Jersey, New York, and Pennsylvania, though she left graduation early to play Peter Pan at the Pennsylvania Youth Theater.
By 1999, though, she'd decided to go all-in on acting again. She showed up on Nickelodeon's The Amanda Show and All That, plus General Hospital, and started carving out a solid voice acting career. She's voiced Kari in Digimon, Koko in Zatch Bell!, characters in Ghost in the Shell: Stand Alone Complex and s-CRY-ed, and even sang as Dorothy in NPR's adaptation of The Wonderful Wizard of Oz.
As of 2006, she's become a fixture in kids' animation, voicing Widget on Nickelodeon's Wow! Wow! Wubbzy!, the title character on Cartoon Network's The Life and Times of Juniper Lee, and appearing on PBS's Clifford's Puppy Days and Nickelodeon's live-action Zoey 101, among other recurring roles.
