Teresa (Y Lung)

Head of the orphanage

Teresa (Y Lung) is the head and heart of the orphanage in Kon Tum. Without her fantastic effort and love for the children, LittleBigDreams e.V. would not exist. After she met her husband, Thin, she decided to dedicate her life to helping children who were in the same situation as she was growing up as an orphan in the area. Even though Teresa has her own biological daughter, Stephany, she treats all the children like they are her own. Teresa is a “Mami” for 73 children.


Head of the orphanage

Thín grew up in the area with this family. He is a farmer and takes care of the land of the orphanage and a couple of fields that Teresa and he own an hour away from the orphanage. Also, he thinks of all the ideas for the construction projects and supervises the processes.
