Local Support

NDSS has more than 375 local affiliates that provide an array of benefits to help better service the Down syndrome community in their local area.  We view our local affiliates as equal partners working on behalf of individuals with Down syndrome, their families, and the professionals involved with their overall welfare. 

Some affiliates are large operations and some are small neighborhood groups.  Although they perform a variety of services, nearly all have a parent support component. Affiliate services and programs may include: new parent support and education, family meetings, sibling and grandparent support, recreational activities, lending libraries, helplines, regional conferences, partnerships with Down Syndrome Clinics, training for medical professionals and educators, Advocacy and Buddy Walks.


If you are having difficulty finding local support using our interactive map below, please check our complete alphabetical list of affiliates by state.
