Members around the world
Our members are constituted PWS Associations representing families around the world. They pay an annual subscription fee based on the number of families in their membership. The subscription year runs from 1 January to 31 December.
Our member associations are subscribed members with voting rights. They are indicated on the map in pink. Use the dropdown to see the associations by continent and use the links to visit the local member website or social pages. Each registered PWS Association appoints Parent and Professional Delegates to be their representatives. When applicable, a Caregiver Delegate is also appointed.
