You could get as many answers as people answering.
In general the top hospitals tend to have the top doctors.
Children’s Hospital, Boston, MA is a top hospital.
Also consider NIH in Bethesda, MD for both excellent doctors ( Dr. Merke ) and cutting edge research.
If your question is part of a broader question in which the answer might determine where you live...... pick Maryland. Montgomery County ( which includes Bethesda, Rockville, Potomac, Silver Spring and more ) has some of the very best schools in the nation. It is expensive to live there however.
In the end, the best doctor is the one that YOU or your child like and feel comfortable with.
