In 1951, a group of concerned parents got together to ensure that their children received the best educational and social services possible. Since then, Arc of Onondaga has been providing quality programs for people with developmental disabilities of all ages.

Arc of Onondaga is one of the largest providers of services to people with developmental disabilities in Onondaga County serving thousands of individuals and their families and employing 500 people. With nearly 40 different sites throughout Central New York, Arc provides a wide array of services including residential, day, employment and clinical, and recreation programs. In addition to these supports and services, Arc operates Arc Contract Services, a vocational program and outsourcing company with corporate partners throughout the region.

A true community-based organization, Arc thrives on community involvement and inclusion, as well as relying on community membership to build its base of support. Its program participants volunteer hundreds of hours in the community each year in support of a wide variety of organizations and causes.

The Arc of New York is the largest not-for-profit in New York State serving people with intellectual and developmental disabilities and their families. The 53 Chapters comprising the Arc of New York are located in every county in New York State. The Organization supports over 60,000 individuals, employs over 30,000 people and has a membership of over 110,000.
