Tumaini Staff – November 2019

The Tumaini team includes professional clinicians, our office team and those who look after our grounds and security.  We are people from many different backgrounds, but with one aim: to serve God’s people working in Africa.

The clinical staff at Tumaini are all professionally qualified, and accredited or licensed by their professional bodies.  In addition they are all missionaries themselves, so they know the joys and challenges of mission life from first-hand experience.
