In 1978, when Community Development (HUD) funds became available, 11 municipalities from the Southeast region of Bergen County, New Jersey (Bogota, Cliffside Park, Edgewater, Englewood, Englewood Cliffs, Fairview, Fort Lee, Leonia, Palisades Park, Ridgefield and Ridgefield Park), decided to pool their allotments and have a collective project of their own, along with other projects for their municipalities. They chose a health project, the Southeast Senior Center for Independent Living (i.e., SESCIL), which provides preventive and maintenance health care services to the elderly on an individual basis.

From its inception to the present, SESCIL has had a community-based policy-making Board of Directors consisting of representatives of the 11 municipalities in the region, and an approximately similar number of health and geriatric professionals, as well as several client representatives. Until July 1, 1992 administrative matters were handled by the County. At that time SESCIL became an autonomous, independent non-profit organization.
