The College of William and Mary in Williamsburg, VA has a graduate program in gifted ed. They also produce quite a bit of curriculum for gifted students. See http://education.wm.edu/centers/cfge/graduate/alumni-features/index.php for alumni experiences. I live nearby which is the only reason I know a little about them.

Best of luck to you!
