The Long Island Association (LIA) is the largest business organization in New York, and the leading organization in the Long Island region. The LIA’s membership is comprised of small and large businesses, labor unions, colleges, universities, nonprofits, government agencies and civic groups, which together employ two-thirds of Long Island’s workforce.

Founded in 1926, the LIA’s mission is to lead the region’s development–bringing together disparate factions within the community to forge regional solutions for Long Island. The LIA also acts as an umbrella business organization, providing products and services designed to assist the growth of businesses large and small. The association is led by a 60-person Board of Directors, which includes the Chief Executives of many of the Island’s principal businesses, universities, and other organizations.
