If you want to work in Philly go to Villanova, if you want to work in D.C go to American. Both schools have a solid alumni network, I can only say how strong Villanova has b/c i'm currently there. I'm sure American has a strong one in D.C though... Villanova has a strong collegial environment, i'v been to two bbal games this year so far! haha
But in the end... you decide where you want to practice. If you were going to boston, you may want to try a boston school, but if not, Nova "may" be better b/c it is closer.
Also you may want to check out the schools IP programs. That could help aid your decison also. First Location, second IP programs.
Good luck.. they are both great choices to have!
