CCP is basically UPMC's network of pediatricians, so they're massive and have locations all over the Burgh. What I like about the McMurray and Castle Shannon offices is that they were, until very recently, an independent practice called Pediatrics South, and their doctors has all been with the practice for many years. Unfortunately they took a huge financial hit during covid and ended up being bought out by CCP/UPMC, but the doctors and staff mostly stayed the same and continued business as usual with a different name.
