Where We Serve
From the favelas of São Paulo to villages days upriver, our work follows the places the church has not yet reached.
Amazon Basin · Manaus
The Arrowhead Project
Reaching the unreached tribal groups of Brazil’s Amazon Basin through evangelism, discipleship, education, health care, and community development. Our goal is a church in every tribe, led by its own people.
- Church planting and the training of indigenous pastors and leaders
- Schools, medical clinics, and clean water systems for the villages
- Discipleship materials developed for each tribe we work with
- Raising up and sending Brazilian missionaries to the tribes

City of Refuge
We give a permanent home to children who have been abandoned or abused, so they can grow up safe, cared for, and in school.
Jim’s Kids Feeding Centers
We serve a hot meal every day to children in the poorest neighborhoods of São Paulo, along with tutoring, games, and job training for teenagers.
Beyond São Paulo
We support the same work in other parts of Brazil, reaching children in Amazon tribal villages, river communities, and the northeast.
