About Interserve USA

Interserve USA is an international, interdenominational community dedicated to making Jesus known in North Africa, Asia, and the Middle East. By sending professionals skilled in healthcare, engineering, business, IT, finance, education, social work, and more, we prepare cross-cultural servants to use their God-given gifts and training to transform lives and communities in partnership with the global church. Since 1852, when women in South Asia launched Interserve, 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.
