Voicecaster
A good company to know about— they cast, they do demos, they offer classes.
Kalmenson
Another great recording studio with classes and demo production.
ASIFA
Did you know that animation voices get awards, too? Of course they do, everyone gets an award in Hollywood. They’re called “The Annies” and the International Animation Film Society sponsors them. Don’t ask me why they’re called ASIFA.
