Great area..I'm in Chadds Ford (CF) just west of Concordville...
... as others have said, wonderful area. Formerly from western PA, I've lived in this area for 25 years and love it. It is commutable to center city Philly, which I used to do, and is also close to other large employment centers such as Wilmington, DE , West Chester, King of Prussia, Malvern, etc.
Concordville proper, generally the area surrounding the intersection of routes 322 and US 1 is in the Garnet Valley district. Unionville-Chadds Ford is the neighboring district and is one of the highest rated schools in the state. If you like just a little bit more diversity, the Kennett School district just a bit west is also very good. Great Valley is just to the north. All of these school districts have top notch facilities, academics and fine athletic programs.
Kids sports are big no matter the sport -- baseball, softball, volleyball, lacrosse, football, soccer, hockey, etc. In addition to school teams there are numerous club programs for just about every sport.
Culturally, Longwood Gardens, one of the finest horitcultural gardens in the country is a few minutes away in Kennett Square. Center city Philly is 45 minutes away with some wonderful museums and historical sites. Beaches in NJ and Delaware are just a few hours away. NYC is a little over 2 hours to the north, DC is a little over 2 hours to the south. Happy Valley is 3-1/2 hours away.
