When Fr. Expedit Sserunjogi served at Holy Family – St. Thomas Aquinas, he expressed concerns about the living conditions of the natives in his Ugandan village — and that’s when Park Slope parishioners wanted to help. Through their offered donations, Fr. Expedit returned home and built a Catholic elementary school. Tim Harfmann spoke to Fr. Expedit, who is visiting the Brooklyn parish for the summer, on how the partnership has transformed his community in Uganda.
