Child Soldier Becomes First Doctor in His South Sudan Town

The boy who fought in a war before he could read is now saving lives with a stethoscope instead of a gun.

Yohanis Riek grew up herding cattle in South Sudan, then became a child soldier during the country's brutal civil war. Today, he's the first doctor his community has ever produced, and he's on a mission to transform healthcare across his homeland.

Riek shared his remarkable journey at a TED Fellows event in July 2025. His path from the battlefield to medical school defies every odd stacked against children born in conflict zones.

After earning his medical degree, Riek didn't head to a comfortable city hospital. Instead, he founded a nonprofit dedicated to bringing healthcare to South Sudan's most isolated communities, places where medical care has been a luxury few could imagine.

His approach goes beyond treating symptoms. Riek's organization trains local community members to become healthcare providers themselves, creating a sustainable system where villages can manage their own health needs.

South Sudan became the world's newest country in 2011 after decades of conflict. The young nation faces enormous challenges, including limited infrastructure and healthcare access that ranks among the world's lowest.

The Ripple Effect

Riek's work represents something bigger than one doctor's mission. By training locals instead of parachuting in outside help, he's building healthcare capacity that will serve generations. Communities that once had zero medical resources now have trained providers who understand their culture, language, and specific needs.

His model proves that sustainable change comes from within. When people take charge of their own health, entire communities transform.

The children who grow up in these villages won't have to travel hundreds of miles for basic care. They'll see neighbors and relatives providing medical treatment, making healthcare feel accessible instead of impossible.

Riek's story shows how resilience can reshape not just one life but an entire nation's future. The boy who survived war is now giving others the chance to survive preventable diseases.

From child soldier to healer, Yohanis Riek is writing a new chapter for South Sudan, one healthy community at a time.
