He is also currently a distance learning student pursuing a bachelor’s degree in Humanitarian and Conflict Response at the University of Manchester in the UK.

Simon Bol Gatwech Buluong
Chairperson of UOCO’s Board of Directors (South Sudan)

Simon Bol Gatwech Juluong

Simon is the Program Manager at CEDS (Centre for Emergency and Development Support, WASH). He is from the Republic of South Sudan and is personally very excited to be part of Tito’s dream.

Like Tito, Simon has a consistent determination and deep interest in promoting education. Before 2013, while working in Wau, Western Bahr el Ghazal, he began his own primary school initiative. He left Wau in December 2013, just one week after the Juba Massacre, fleeing because of the war. When he returned to the area in July 2023, he was overwhelmed with emotion—the school had expanded into a high school, and the primary school had grown to include many more classes. His reflection: “We can do the same!”

Chol Ngut Khor

Chol Ngut Khor is a Field Monitoring Assistant at WFP South Sudan. He is from the Republic of South Sudan and is a supporter of UOCO. He has learned from Tito how he came about this dream, and he was touched by the story. South Sudan has been devastated by conflict over the years, which has left many children orphaned. Chol is happy that Tito has this dream to be the hope of these children by building a school to accommodate them and restore their hope and future.

Chol writes, “We all have dreams, but I am so happy to be part of this unique dream of Tito’s! Tito has drawn his dreams from real life experiences by helping an orphan child, which later opened his mind and made him think bigger for the rest of the children. His big heart led to UOCO. May God bless this dream.”
