Established in 1994 as the UP Manila chapter of the system-wide volunteer service organization, Ugnayan ng Pahinungod/Oblation Corps, the Office of Ugnayan ng Pahinungod-Manila provides international support to volunteer activities where UP Manila constituents get to share more of their skills and talents with less privileged Filipinos.
Its current programs are clustered into three: Educational Program (Teachers Development Program, Tutorial Services Program); Community Health Programs (Health Missions, Health Education and Training, Emergency Room Volunteers Program, Hospice Care Program); and, Social Services Programs (Summer Immersion Service Program, Program for the Streetchildren, Livelihood Program, Disaster Preparedness and Risk Reduction Management Program, Environmental Health Education Program). There is one stand-alone program: Advocacy Program. Its volunteers come from the ranks of the health professionals, personnel, students, alumni, and other willing volunteers from sectors outside the University. The Ugnayan ng Pahinungód-Manila has served more than 137,000 Filipinos.
