WorldChanger Tanzania

Africa · Tanzania

In the summer of 2015, Andreas and Tanja Walther went on a medical mission to Tanzania / Serengeti. But it was God's plan that it would not remain a simple medical mission. Through encounters with the local people, God opened their hearts and a new vision was born: WorldChanger.

Today, our team serves in Mugumu/Serengeti through education, orphan care, agriculture, and medical programmes — bringing God's love in a very practical way to the most vulnerable.

Grow With Us

To feed more and more children and students, we are increasingly growing our own food. Sustainable farming gives our community food security and teaches practical life skills.

"Go therefore and make disciples of all nations, baptising them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age."

— Matthew 28:19–20

Mission & Discipleship

Every week our WorldChanger team goes out onto the streets of Serengeti Town and into the surrounding villages — bringing the best news in the world, praying for healing, and distributing soup to the poorest of the poor.

The People Behind the Vision

Our Leadership & Management Team

Together with our young, dedicated African team, we live out the vision and mission God placed in our hearts: to bring His love to people in a very practical way.

Alongside the leadership team, we have over 20 full- and part-time staff, plus 15 to 20 local volunteers working across all areas of the ministry.

Our major construction project in Tanzania

We have purchased a plot of land in Mugumu where we are building a vocational training center, dormitories for the students, shelters for orphans, a chapel, and an administration building.

So far, thanks to donations alone, we have been able to build a chapel, a school building, an emergency shelter for orphans, and a kitchen building. But we haven't reached our goal yet.

If you, like us, are passionate about helping young people find a way out of poverty through education, we would be very grateful for your support.
