The National Down Syndrome Society is a Washington, DC-based nonprofit focused on improving the lives of people with Down syndrome and their families. It pursues policy changes, provides education and practical resources, and engages with local communities to shift public perceptions toward greater inclusion. These activities position NDSS as an advocacy and resource hub within the disability nonprofit sector. Its primary audience includes individuals with Down syndrome, their families, and communities influenced by disability policy, with involvement from policymakers and supporters nationwide. In 2025, LuMind IDSC Foundation merged into NDSS, broadening its scope to include Down syndrome research collaboration. The organization is mid-sized and based in Washington, DC, with a national footprint in its activities.
