Our People

Board of Directors

Gail Wagner, MD - Founder & President
Gail Wagner met young community organizer Daniel Ogola in Nairobi's Kibera slum in 2002.  The two discussed an audacious idea for a comprehensive community health care system in Dan's impoverished rural home near Lake Victoria. They began with a trip of North American based medical volunteers.  

Fourteen years later, Tiba Foundation helps support three outpatient clinics that treated 24,000 people in 2010, a phenomenally successful community health worker program in the villages that is changing not only the lives of patients, but the productivity of a community.  The first phase of a beautiful new community hospital was opened in July 2011.  Gail recently retired from her position as an oncologist at Kaiser Permanente. She describes the work she does in rural Kenya as "the most important thing I will ever do in my life."
