In becoming a voice-over artist for animation, she was mentored by Daws Butler. It was at Hanna-Barbera Productions where she began her professional voice acting career (in which she played Gloria Glad in that studio's animated adaptation of Richie Rich). Outside of The Simpsons, her voice credits since then have included Daffney Gillfin in Snorks, Bright Eyes in the 1986 series Pound Puppies, Mindy in the Warner Bros. animated series Animaniacs, and Chuckie Finster in the Nickelodeon series Rugrats (taking over the role in 2002 after the retirement of Christine Cavanaugh).
Her Disney roles include voicing the Toon Shoe in Who Framed Roger Rabbit, Pistol Pete in Goof Troop, Fawn Deer in Bonkers, Rufus in Kim Possible, Todd Daring in The Replacements, Pumbaa Jr. in Timon & Pumbaa, Phantasmo and Shortstuff in Lilo & Stitch: The Series, and Goldilocks in The 7D. She also provided an additional voice in The Little Mermaid.
