I don’t know about Shenandoah’s acting program; I only know some about about their MT program. However, I know a lot about UArts, as my D is a junior MT major there. We are thrilled with it! The thread below may be a good place to start, at least from my D’s and my perspectives:
If you have other questions or would like to be connected to my D, feel free to PM me or ask me to PM you if you don’t have enough posts to PM yet.
