Dr. Tom Catena is a Catholic missionary from Amsterdam, New York. In Sudan’s war-torn Nuba Mountains, where bombing has been part of life and aid has been restricted, he became the only doctor permanently based there. Working at Mother of Mercy Hospital, he was on call 24 hours a day, seven days a week, caring for more than 750,000 people. Patients have been known to walk up to seven days to see him. He was estimated to treat around 500 patients a day and perform more than a thousand operations a year. In 2017 he received the Aurora Prize for Awakening Humanity. Plenty of people could have left. He stayed. Love often looks like simply staying where the need is.
