Wouldn’t change a thing

We are trying to achieve a world where negative outdated perceptions of Down syndrome are a thing of the past.  We do this by creating and promoting projects designed to directly challenge outdated perceptions.  Our projects are designed to be uplifting, emotive and positive; offering insights into how enjoyable life for all those associated with the condition can be.  Our intent is to leave those who view our work feeling challenged and changed making them more willing to accept those with Down syndrome and to consider them as valid members of society, as schoolmates, as work colleagues or as employees.


Down Syndrome Research Foundation


Our mission is to undertake research which will help to identify and develop interventions which alleviate the medical, physical, developmental and cognitive conditions associated with Trisomy 21 which are collectively described as Down’s syndrome.  We understand the challenges, talk to the researchers and initiate important research.
