Hello Forito,
If you're only looking at SUNY schools Phi Sigma Sigma has quite a few chapters at them. We are fairly strong in the state of New York as a whole as we were originally found at Hunter College and spread out from there (unfortunately our Alpha Chapter is close
Here are the SUNY schools that have Phi Sigs: Buffalo, Binghamton, Brockport, Albany, Stony Brook, Oswego, Oneonta, College at Buffalo, College-Cortland.
If you want to consider other schools in NY state we also have chapters at Iona College, U of Rochester, Syracuse (just recolonized with 90 women), Clarkson, Pace, Hofstra, Long Island-CW Post, College of Staten Island.
My suggestion is keep your options open for schools. Look for the school that is best for helping you acheive your goals in life and then see what sororities are there.
