Yes, but its only a medical school:
Correct, the Milton S. Hershey Medical Center (near Harrisburg).
Note also that Penn State acquired a Law School within the last few years: thingyinson Law School in Carlisle. There had been some recent debate about moving the facility to University Park (State College). Please note that this former private Law School, is not affiliated with thingyinson College, also located in Carlisle.
While Penn State has branch campuses, some quite small, comparatively; those units and the main campus itself, are NOT part of the 14 campus (with a couple of branch campuses themselves) of the Pennsylvania State Higher Education System.
