The University of North Carolina-Chapel Hill and the University of Texas-Austin will have the strongest Philosophy departments overall. Rice, the University of Virginia, Wake Forest and William and Mary will also be good.
While not considered quite “elite”, the University of Kentucky has a respectable Continental Philosophy faculty. Worth a look if you wish to look at Southern universities.
You should also check out LACs, like Sewanee, Davidson etc…
Also, if you are willing to consider California and the SW, you have several other options such as the University of Arizona, Cal, UCLA, UCSD an UCR, all of which have large and well respected faculties. The Claremont Colleges, especially CMC and Pomona, will also offer excellent options. Finally, the University of New Mexico also has a solid Continental Philosophy faculty.
