I have an interesting, off-the-wall suggestion for you. The College of Wooster in northern Ohio might be worth considering. They have a voice performance major embedded in their music program. (See link below.) Also, the campus is home to the very respected Ohio Light Opera, a professional company that does summer performances. ... Wooster is a wonderful academic school, second-tier US News & World Report and featured in the book "Colleges That Change Lives." Give it a look--and good luck to you!
