Hi Lil Sister!
I didn't go to school in NY, but I just checked
www.alphaphi.org and found that Alpha Phi has chapters at SUNY Albany, Binghamton, Buffalo and Cortland. There are also Alpha Phi chapters in NY at Cornell, Hofstra, Rensselaer, Syracuse (our Alpha chapter), Plattsburgh State and U. of Rochester.
If you ever have a lot of time on your hands, you could probably check out the websites for the various NPC organizations because I think most of them probably list collegiate chapters like Alpha Phi does. I would guess that many of them also provide links to the collegiate chapters, so you could visit the web pages of the actual chapters and get a feel for the different organizations in NY. Good luck!!!
