Indeed it is
Her voice work, as well as the work she's done with Marvel and DC (if I remember right, she created the Rubber Band Man for Static Shock), will stand as testaments of her character.
In a semi-related note:
IMDB lists her as having been a beta tester for TMNT III: Radical Rescue. I find this interesting, especially since there's been recent talk about the game here. Can anyone confirm this?
