About Us

Back Ground

In 1986, Mrs. Tsehay Roschli founded Selam Children’s Village with 23 orphans and 4 workers in order to provide necessities and a family for children who lost their parents due to the drought that occurred in the northern part of Ethiopia. Following their daughter’s path, her parents, David and Marie-Louise Roschli settled in Ethiopia in 1989 and began the ground work for the technical and vocational center. Over the year, Selam continued to grow, through supporting many people and employing hundreds.
