“Small acts, Big impact”
About Us
What is Sesawi?
Sesawi (mustard) grows from a tiny seed into a large, strong plant — a picture of how small acts of faith and action can carry great potential and benefit many people.
We were born from the dream of a young Indonesian who longed to empower the children of Sumba with better-quality education. Sumba Bermain is based in West Sumba and was founded by Yuliner Dejoice Yestiyani, who leads the foundation.
