The Tri-Co linguistics department is phenomenal. Tri-Co means it’s shared between Bryn Mawr, Haverford, and Swarthmore Colleges (http://www.brynmawr.edu/catalog/2014-15/areas_of_study/linguistics.html)
I know majors who have gone on to work in language data programming to pursuing PhDs at top-notch programs domestically and abroad. Because you’re pulling from the resources of three colleges, you really have a breadth of faculty and topics available to you. You can also take courses at Penn through the Quaker Consortium.
