Our Team 

Committed People, Real Impact

At Water for South Sudan, our team isn’t just a list of names. We are a community of passionate professionals, leaders, and field-workers united by a shared mission:

to bring clean water, hygiene, and sanitation to remote villages across South Sudan—and to build sustainable hope for future generations.

From our field operations in Wau to our administrative and development staff in the United States, each person brings unique skills, lived-experience, and dedication. Together, we plan, drill, rehabilitate, and maintain wells; coordinate hygiene and sanitation education; manage vital donor and data operations; and build partnerships that make long-term impact possible.

Every team member, whether on the ground or behind the scenes plays a crucial role. This diversity of backgrounds and collaborative spirit enables us to transform tragedy into opportunity, and water scarcity into lasting community resilience.
