"DSDN is the largest national organization supporting new and expectant parents with a Down syndrome diagnosis. The mission of the Down Syndrome Diagnosis Network is to connect, support, and provide accurate information to parents - and the medical professionals who serve them - from the time of diagnosis through age 3, while fostering the opportunity for life long connections. Our vision is that every Down syndrome diagnosis will be delivered in an unbiased, factual, and supportive way every time, and that families can quickly find meaningful connections." https://www.dsdiagnosisnetwork.org/
