MPI seeks college students and recent college graduates to execute community development programs in Nicaragua and Ecuador. Program Directors serve for thirteen months, volunteers work for any amount of time from a long weekend to multiple months.

MPI directs its efforts towards communities in need: communities with inadequate access to basic education, healthcare, and recreational resources. MPI aims for a holistic approach to community development, working with people of all ages in various aspects of their lives. This broad approach enables those with diverse passions and skills to work together towards providing a targeted community with the resources to serve its specific needs. For example, to better serve the healthcare needs of a targeted community, a holistic approach involves teaching health classes in the schools, providing access to clinics, and offering recreational activities that increase physical and mental health.

MPI believes in the initiatives of its members and volunteers, thereby allotting them with a large amount of responsibility and independence. MPI seeks individuals who have true hearts for service, strong desires to work as part of a group, and aspirations to be challenged on a daily basis.

College campus chapters and other domestic participants, who work towards similar goals by raising awareness and support for the international team, complement the MPI international service team.
