Our friends daughter is a senior at Point Park in Pittsburgh. You mentioned dance therapy. It is a very serious dance school and number of students go there with the the hope to dance professionally. Obviously not all of them do. Our friends daughter is trying to dance professionally but is also interested in a career that involves dance and working with kids with special needs.
Point Park is probably 5-6 hours from metro DC, right in downtown Pitt. I believe pyschology is one of their stronger programs and they offer a five year masters.
