An International Community
Membership & Local Support
IPWSO was established so that PWS associations, families, clinicians and caregivers around the world could exchange information and support and have a united global voice under one umbrella. Please see our Constitution for further details.
All fully subscribed country members with their own constituted PWS Association pay an annual subscription fee based on the number of families in their membership. The subscription year runs from 1 January to 31 December.
