January 2001, Madison County ARC and The Arc of Cortland County merged to become Madison Cortland ARC. The Arc of Cortland County was founded in 1966 and Madison County ARC in 1968. Both agencies were founded by a group of parents who were concerned about their children with developmental disabilities. Those parents fought for services for all children with disabilities and they were pioneers paving the way for services in New York State.
In 2014, Madison Cortland ARC entered into a trademark agreement with The Arc US and became The Arc of Madison Cortland. The Arc of Madison Cortland is a chapter member of NYSARC, Inc.
The Arc of Madison Cortland is a strong parent/family based organization. In fact, two-thirds of the Board of Directors are relatives of a person with a developmental disability. They offer their unique experiences to ensure the best quality of support and services The Arc can provide.
