A strong program is usually a fairly subjective evaluation. As for PD assessments, always ALWAYS do a rotation with a possible program of interest. With AOA residencies, this seems to be the golden factor PD's go by...
My best friend from med school is a PGY 3 at Mt. Clemmons ENT. If you want to talk to him PM me and I'll try to get you into contact with him. The ENT program at my hospital is solid too.
