Well, I happen to know people that have done the GCS program and have gone on to sociology doctoral programs. I myself am waiting to hear back from a communication & rhetoric program and have been accepted to an African American studies program after finishing up the GCS program at Simmons. I would suggest that since you know what kind of program you want to do, you tailor your experience at Simmons accordingly. Seek out sociology professors as your mentors (like prof. Puri, who directed the GCS program for the first year I was there) and apply to TA for a sociology class. Basically, you will want to sell yourself to doctoral programs as someone who has both pursued sociology and has a little something extra to offer and I don't think that can hurt, it may very well help you stand out from straight up sociology B.A.s and M.A.s Good luck!
