Arcadia is only 30 minutes from the city. There is a local train station that will take you directly to center city, which is only a mile from the school. I actually go there now so you can always PM me and I can try to explain further to help your decision!
& Philadelphia has more than 5 major hospital systems (Temple, Drexel, UPenn, Jefferson...) in the area so there are MANY opportunities here, too! This place is RICH in healthcare services.
