Peggy O'Neal got her start in voice acting when she was first seen in three episodes of seaQuest DSV and then went on to do ADR on Dawson's Creek, Dark Skies, Walker, Texas Ranger. Then she took on a voice acting class where she was taught by Susan Blu leading up to her anime roles upon her classmate being the girlfriend of Saban worker Paul Di Franco who did all of the casting for the Saban Entertainment shows. During her work on Saban Entertainment's shows, Peggy considered her Shinzo character Yakumo Tatsuro as a big break for her. Some of her anime projects had her playing the sister of some of Dave Wittenberg's characters while also mentioning that some of her characters would often be the love interests for Steven Blum and Crispin Freeman's characters.
When not doing voice acting, Peggy works as a part-time teacher at Moorpark College where she teaches acting to her students.
