Head of the orphanage

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.

Meet the German Team


Founder & chairwoman

Klara Kattwinkel is currently working as a psychologist for children and adolecents at the hospital and as a self-employed counsellor. Along her journey, she dedicated most of her time to volunteering and working with children in need across various contexts in Germany, the Netherlands, and Asia. Klara actively engaged in Impact Startups and initiatives, taking the lead in organizing fundraisers and initiating her own projects. Her initial fundraising project for Teresa’s orphanage in 2019 and her experiences in Vietnam deeply influenced Klara. During that time, she formed a genuine friendship with Teresa, who’s a true hero in her eyes. The way Teresa tirelessly worked for the cause inspired Klara to take action. Armed with the “do-it-yourself” mentality and fueled by plenty of passion, she rallied an awesome team together and built LittleBigDreams e.V. from scratch, all to support Teresa in bringing her incredible vision to life.
