Born in Ireland in 1973, Sister Orla Treacy was, at a young age, inspired by the lives of service and compassion of her teachers who were religious sisters. After studying to become a teacher of religion, she joined the congregation of the Institute of the Blessed Virgin Mary (IBVM), known as the Loreto Sisters. In 2006, while teaching and offering pastoral care in Ireland, Sister Orla joined other Loreto Sisters who were starting a new mission in Rumbek, South Sudan–an area besieged by civil war and violent inter-clan conflict. Touched by the plight of girls who were being forced into early marriage and denied the right to an education, she took action. Sister Orla and the Loreto Sisters started a girls-only boarding school with 35 students. Today, Sister Orla serves as the head administrator of the Loreto Rumbek Mission in Maker Kuei, overseeing a boarding secondary school for girls, a co-educational primary school, and a women and child-centric primary healthcare facility. Sister Orla is a part of a diverse multinational team of religious sisters, educators, nurses, and other support staff, who all share a vision for improving the lives of the most vulnerable in the community. Despite the devastating consequences of war in Rumbek, and the many barriers to women and girls in the community, Sister Orla remains filled with hope, and the Loreto Schools stand as a beacon of light for future South Sudanese generations. She continues to work in faith, striving for a world in which girls are not forced into marriage, are allowed to complete their education, and can pursue their dreams.
