Yes, Pittsburgh has a very good pediatrics program. Though there aren't really formal rankings, I know many faculty who consider it to definitely be top 20. And for some things (transplant) they're one of the top dogs nationwide.
I don't have that much experience there, as I only spent an afternoon interviewing there. I remember somebody on here did an away Sub-I there, so they could answer better.
The people I met with (chiefs, faculty, & PDs) were non-malignant. While the facilities are nothing to write home about, they will be in a couple years. The blueprints for the new children's hospital there look amazing.
From what all the residents say, the diagnostic referral service sounds liked it's well liked and good for resident education. One of these attendings is the author of one of my favorite peds books (Atlas of Pediatric Physical Diagnosis by Zitelli).
I'm still trying to decide where to rank it myself. Does anybody else who has spent more time there have some insight?
Thanks!
