Cornell Cooperative Extension of Suffolk County is located on the eastern half of Long Island, New York. We have several sites around the county. These multiple sites not only allow us to bring programming from one end of Suffolk to the other, but also allow our communities to come visit us. Below you will find the information for where our offices are housed, how to contact us at the various locations and directions to get to us. We hope to see you soon.
