About Interserve USA

International Service Fellowship (Interserve USA) is an international, interdenominational community dedicated to making Jesus known in North Africa, Asia, and the Middle East. Sending doctors, nurses, social workers, engineers, business people, digital nomads, educators, and more, we prepare cross-cultural servants to use their God-given gifts, training, and professional skills to transform lives and communities in partnership with the global church. Since 1852, when Interserve was launched by women in South Asia, we have remained committed to caring for the poor and marginalized and sending people to live and work in places where few, if any, have encountered Christ. Our U.S. office is one of 14 national offices working together to mobilize multinational teams.
