Hi Theresa,
Well, I’m a bit biased, but I highly recommend University of Maryland. Rebecca Anstine Smith is the teacher there, and Alice Chalifoux gives monthly lessons to all harp students.
Look into Boston University…GRRREAT Harp Program including Lucille Lawrence as head of staff (who was once married to Carlos Salzedo). Also, try http://www.Collegeboard.org for an advanced search of all the programs you want…great site.
