Welcome to Cornell Cooperative Extension of Suffolk County

 Cornell Cooperative Extension of Suffolk County assists and educates residents, businesses and professionals in a broad spectrum of topics by providing research-based information on parenting, diabetes management, nutrition and wellness, horticulture, environmental protection, marine restoration and sustainable agriculture.

Experts from our four main program areas—Family Health and Wellness, Marine, Agriculture and 4-H Youth Development—reach tens of thousands of adults, children, professionals and businesses each year.

We bring this free and low-cost knowledge directly to people at workshops, children’s camps, libraries and schools. We also work one-on-one with fisherman, farmers and growers to strengthen these industries, bringing tourism and advancing economic development. CCE programs have had a significant impact on communities and industry in Suffolk for nearly a century.
