The Main Line is the best area for people in healthcare. It stretches from Philadelphia to Lancaster. Obviously, the closer you get to Philly the more dense in population it becomes. As you get further west it becomes more suburban and by the time you hit the Lancaster area it's mostly farms (Amish country). I think you'd probably like the western part of Chester county and the Lancaster area. The Hollywood Casino is just north of there and the Valley Forge Casino is about 45-60 mins northwest.
