You have to include Pitt as one of the top peds anesthesia fellowship programs in the country. The attendings there not only wrote some of the classic texts for peds anesthesia, but they remain on the cutting edge when it comes to perioperative management of some of the most difficult cases. In addition, the fellowship is the first-ever to have been established in the country.
In the pediatric world, Children's Hospital of Pittsburgh is world-renowned by pediatricians for its pediatric transplants, ENT expertise, and PICU care, among other non-surgical specialties. We all have to admit that every program out there is second to CHOP and Boston Children's. However, a few programs can be considered "little brothers" to these fine institutions, and these would be Pitt, Cincy, JHU (and maybe to a lesser extent--Seattle, Children's National in DC, UCSF, UCLA, McGaw, Medical College of Wisconsin). Another crude measure of a good peds program is if they have their own free-standing children's hospital.
My humble opinion...
