MAHI International came to be simply through the inspiration of experience.  After years of visiting the Micronesian Islands, working there, and learning to love the people and their culture, founder John Schroer, along with several other dedicated and passionate individuals, developed a great awareness of the needs of the people in these communities. 


MAHI International, which stands for Missions Across His Islands, is a Christian-driven non-profit 501(c)(3) organization based out of Southern California.  We welcome you to learn more about the heart of MAHI International.
