Addressing Autism: An Evening with Ron Suskind
April 1st, 2015 at 5:30 P.M.

students give backCongressman Chaka Fattah, will be hosting an event on April 1st to kick off Autism Awareness Month. Everyone is welcome; Suskind’s presentation will be as inspiring and entertaining as it will be informative.

Researchers at MIT, Cambridge, and Yale have come together to collaborate over a new way to address autism called “Affinity Therapy” that uses the child’s own interests to stimulate social development. The idea behind this study has a unique source; it was seeded by Ron Suskind, the father of an autistic child whose 20 year journey together illustrates the incredible dedication and understanding many parents face in finding ways to connect. His experience was translated into an international research collaboration that is changing the lives of those affected by Autism Spectrum Disorder.

Join Ron, the Pulitzer Prize winning journalist and bestselling author, as he explains the development of Affinity Therapy. You’ll have the opportunity learn more about what you can do as a scientist, family member, or caregiver to improve the lives of those affected by Autism Spectrum Disorder.
