Having done my Master's work at the University of Washington, I might be able to answer some of your questions. Jane Eaglen, Joyce Guyer, and Tom Harper are the instructors currently.
Quite honestly, the future of the voice program seems to be a bit unclear. The budget for opera seems to have decreased (surprise surprise) and with a new dean of the School of Music in place, only time will tell what will happen.
I hope I haven't stepped on any toes, and if I did please don't arrow me
Good luck!
