I am a homegrown Philadelphian who attended public schools both in the city and in the suburbs (Cheltenham HS). I went on to the University of Pennsylvania and other than a two year stint in New York City have lived here. Philadelphia is a great place to raise a family. There are a number of "high-end" communities both in the city and in the suburbs. If you like city living and all the amenities it offers I'd suggest the Rittenhouse Square area, Society Hill, or Chestnut Hill. Great suburban areas are Abington and Cheltenham townships to the north and the Main Line to the west. The best schools for these areas are privates schools. Philadelphia's rich Quaker tradition has created some of the best private schools in the country: Germantown Friends, Friends Select, Friends Central, and the William Penn Charter School for example. There are many other excellent private schools. Among them are St. Peters, Baldwin, Agnes Irwin, Episcopal Academy. There are many more and this link will lead you to more http://www.isconsortium.org/schools.htm.
Additionally, Philadelphia offers wonderful cultural institutions and museums. Not as overwhelming as our New York neighbor to the north, Philadelphia boasts world class classical music and music education; renowned art museums and art education, the fabulous Franklin Institute and the University Museum of Archaeology and Anthropology at Penn. We are not all stuffy either. There's a terrific zoo, great sports teams, loads of parks, bicycle trails, great restaurants, and of course history. You will probably get tired of hearing about "Philadelphia Firsts": first zoo, hospital, post office. If Ben Franklin started it, it's here.
I would be happy to provide additional information and hope that you will find what you want in the Philadelphia area.
