We are a local chapter for the National Prader-Willi Syndrome Association (PWSA USA) operating in Oregon and Washington. We also offer assistance to people in neighboring states. Our mission statement is:

Prader-Willi Syndrome Association of Oregon and Washington is an organization of families and community members working together to raise awareness, offer support, provide education and advocacy, raise funds, and promote research to enhance the quality of life of those affected by Prader-Willi syndrome.
