Well, you're in the wrong forum! We in the Lehigh Valley do not consider ourselves a Philadelphia suburb.
Lehigh Valley hospital and St. Luke's hospital have excellent reputations and are located in Allentown and Bethlehem. Southern Lehigh school district is rated very well and is within 15 minutes from either hospital but not in either city. There are a few clumps of townhouses that have been built in the last 6 years in Center Valley. Not sure of your price range but the location is what you are looking for.

C'mon over to the regular PA forum for other opinions!
