Get to know us better!

13Aid to the Developmentally Disabled is a nonprofit organization that was established in 1980 by family members who were concerned about the physical and emotional decline of patients compelled to live in crowded institutions. These family members believed that appropriate treatment and training in a warm, sheltered, homelike environment would enhance their physical and emotional growth. With the support, funding and licensing of New York State’s Office of Mental Retardation and Developmental Disabilities (OMRDD) and the Office of Mental Health (OMH), Aid to the Developmentally Disabled came to life.

In March of 1984 we opened our first residential program in the hamlet of Northville, in Riverhead Long Island. As a result of the initial success, ADD rapidly grew into a multi-service organization providing residential programs, supported apartments, clinical supports and case management services for the mentally retarded, mentally ill and dual diagnosed adults. Aid to the Developmentally Disabled presently operates thirty residential programs in locations throughout the North and South Forks of Eastern Long Island, with several additional programs in the planning stages.



DSCN2396We believe that all individuals have the right, to the extent of their ability, to live in the community and enjoy the benefits and amenities of living in society.

Our purpose is to recognize and identify the special needs of the mentally and developmentally disabled persons and to provide them with a superior professional system of care and services in a homelike environment.

Our residences offer improved services and innovative programming and treatment techniques so that each resident may be given the opportunity to:

  • Develop active daily living skills
  • Develop creatively, motivated by the need and desire for self-improvement.
  • Develop inter-personal relationships that promote social trust and personal growth.
  • Live in dignity in a minimally restricted setting so as to enable them to function independently and constructively.
