We Are Stronger Together

PWSA (USA) is a community of families, professionals, and organizations committed to providing support and hope to those affected by Prader-Willi syndrome. Together, we are showing the world children and adults with PWS need not be defined by their diagnosis.

Family Support

PWSA (USA) supports individuals diagnosed with Prader-Willi syndrome, their families, and care providers with critical information and resources. We educate medical providers, educators, and professional care givers about PWS and how to best support individuals with the syndrome.



PWSA (USA) seeks to support research projects with the potential for immediate and high impact for the PWS community. The goal is to fast-track better treatment for the syndrome, and we proudly collaborate with partners representing pharmaceutical companies, research universities, and more to achieve that goal.

Advocacy & Awareness

Raising awareness and effective advocacy are critical to effecting positive change in and for the Prader-Willi syndrome community. PWSA (USA) is committed to empowering individuals with PWS and their families with resources and tools such as the Public Policy Action Center.
