Where can i find a public clinic at NYC?

Answer 1

If you live in Manhattan, you can go to one of the Ryan Centers.
They have one in the Upper West Side/Harlem, one in Midtown/Chelsea and one in the East Village/Lower East Side. You may have to prove that you live in the neighborhood where the clinic is to get treated. I couldn't go because I live in Brooklyn. They accept payment on a sliding-scale based on income and family size if you don't have insurance. They also take Medicaid, Child Health Plus, Family Health Plus and ADAP Plus.

The website may be under construction but it still gives you the phone numbers:
