The Sri Lanka Twins Organization began at a kitchen table in 1993. Identical twins Upuli and Chamali Gamage wanted to find others like them — twins, triplets, multiples, and the families who held them together. Three decades later, that small idea is one of the world's largest organised twin communities.
Upuli and Chamali Gamage grew up sharing every milestone — and noticing how few resources existed for twins in Sri Lanka. They founded SLTO on 23 August 1993 with one belief: that families of multiples deserve community, recognition, and a platform.
Over three decades, the sisters have led the organization to host the world's largest twin gatherings, form Sri Lanka's first sporting teams composed entirely of twins, and represent the country at international festivals from China to the Maldives.
They continue to lead SLTO from its headquarters in Boralesgamuwa, where Founder's Day is celebrated every August.
To unite the local and international multiples and establish the world as a trouble-free and victorious place — while developing the educational, economic, and social aspects of the less privileged multiple families and thereby contributing to national development.
We want every family of multiples — parents, siblings, twins, triplets — to be seen as a family that needs and deserves a helping hand. Through shared culture and shared skills, we believe we can build cohesiveness between countries.
