NADD, also known as The National Association for the Dually Diagnosed, was founded in 1983 as a not-for-profit Association. The catalyst for the founding of NADD arose from the need for an open forum to promote and exchange of ideas, principals & concepts concerning individuals who have the co-existence of ID/D and mental illness.
NADD has been growing at a steady pace since its inception. We are now recognized as the leading organization providing conferences, educational services and training materials to many thousands of people in the United States and world-wide. Through the dissemination of cutting edge knowledge, we have been influential in the development of appropriate community based policies, programs, and opportunities in addressing the mental health needs of persons who have ID/D.
NADD has been successful in promoting services that bridge the gap between the mental health and developmental disabilities structures. The division of responsibility between the mental health and Intellectual and Developmental Disabilities service systems has resulted all too often in a denial of comprehensive care and treatment for individuals who have ID/D concurrent with a serious mental health problem. NADD is a national leading force advocating on behalf of individuals who have mental illness and ID/D.
NADD has grown rapidly since its founding in 1983 and is now represented in every state in the United States and in Canada, Australia, Japan as well as in Europe.
