Joe Brewster - Director

Joe and his wife, Megan, have served on the mission field since 2003 in the jungles of Peru with brief stints also in Bolivia and Brazil. Their ministry has been focused on taking the gospel to the least reached tribes of the Amazon Basin, and they have worked to complete that task in partnership with existing tribal believers.

Joe and his team focus not only on discipleship and evangelism but also on small business initiatives geared towards facilitating tribal partners as they seek to fulfill God’s missionary call in their own lives. They currently live in Colombia, where they are also raising their three children: Susanna, Caleb and Isabel.

Henrique Terena - Director

Henrique serves on Alteco’s Board, bringing depth and the perspective of an Indigenous leader from the Terena people of Brazil. A supporter and facilitator of the Three Waves Movement since its inception, he has also been involved with the Trans-Amazon Network for many years, sharing experience from Brazil with others across the Amazon region.

Henrique became a Christian at age nine during a Vacation Bible School led by missionaries in his village. His commitment to sharing the Gospel among Indigenous peoples led him to become involved with a discipleship training center in Brazil, which prepares young Indigenous leaders for ministry. He and his wife, Corina, served there for 21 years, and his experience includes serving as associate director of a Bible school.

Since 2002, Henrique has served as president of CONPLEI, a network of more than 100 ethnic groups and 1,800 Indigenous pastors and ministry leaders in Brazil. He also advises Brazilian and international missionary agencies and helps national churches better understand ministry among Indigenous peoples.

Henrique and Corina have two children, Elianai and Eliel. Together, they train and encourage Indigenous ministry leaders. They joined South America Mission in 2022, seeking to strengthen Indigenous networks, develop additional training centers, and bridge the gap between national and Indigenous churches so that unreached peoples across South America may hear the Gospel and respond to the Great Commission.

Paul Johnson - Chairman Emeritus

As founders of Alteco, visionary facilitators of the Trans-Amazon Network of Christian tribal leaders, and initial innovators of the Three Waves Movement across the Amazon region of South America, Paul and Robin have celebrated the privilege of watching God bless this movement since its inception.

For many years, Paul served in the dual role of President of Alteco and Coordinator of the Three Waves Movement. Following Christ’s model, he stepped back to “open up space,” enabling partners and younger leaders to become replacements and successors. Currently, he serves as Chairman Emeritus of Alteco.

As advocates for the movement, Paul & Robin passionately strive to challenge and inspire the Bride of Christ, the Church, in both South and North America. Endeavoring to harness the wisdom and insights learned from 50+ years of focusing on the Amazon, they currently engage in writing and publishing stories of God’s faithfulness and the Gospel’s transformational power. Goals include sharing insightful Biblical paradigm shifts in global mission, producing original missions challenge music, and mobilizing younger generations.

Paul and Robin gratefully claim as their own the amazing spouses of their three children and dearly enjoy spending time with their nine grandchildren.
