The Professional Organization for Nurses Serving Individuals with Developmental Disabilities 

D.D.N.A. was incorporated in 1992 as a non-profit professional nursing organization founded to meet the professional needs of nurses serving individuals with developmental disabilities. 

Governed by a five-member Board of Directors consisting of the elected officers, D.D.N.A. represents the collective interests of its members through a national structure and regional networks.

D.D.N.A. prides itself on advocating, educating, and celebrating the unique and specialized role of the nurses who serve people with developmental disabilities.

The East Tennessee Network of DDNA was established in 2005 by Chattanooga area nurses for the purpose of promoting education and awareness of the Developmental Disabilities field of nursing.
