Dr. Kingsley Kabari, D.C.

An advocate for health and education, Kabari was born in Nigeria in the midst of upheaval and civil war. After years of living in a refuge camp, he immigrated to the United States at the age of 15, where he attended school for the first time while also working to help support his family.

Denis F. Okema

An advocate for Human Rights and Peace, Okema was born in Gulu, Uganda. He was abducted at the age of 9 and spent six months in captivity as a child soldier before escaping.  One day he and several other orphaned children were found by Abitimo Odongkara, herself a Ugandan refugee, who had returned with the hope of founding a school.  Denis was among the first students in what later became the Upper Nile Institute for Appropriate Technology School (UNIFAT) and has worked closely with Gertrude’s students in helping support this school. A motivational speaker working with Civil Society, Okema shares expertise on The Effect of War on Children, Using Social Media for Social Change, Justice and the African Experience, Methods of Conflict Resolution, Effects of Conflict on Economic Empowerment and Sustainability, The Oral Traditions of African Folktales.


Rebecca Abitimo Odongkara

Rebecca’s family was able to escape to the USA as refuges from the Ugandan reign of terror brought on by Idi Amin. However, she never forgot the suffering her friends endured, and after finishing high school she earned a Bachelors of Arts in Special Education at Antioch College. Upon the death of Amin in 1986, she returned to her home in Northern Uganda and started teaching local children; her first classroom was the open space under a shade tree in the village of Otwee. Violence was still prevalent throughout the country, and most of her students had never known peace and security; nor did they have the most basic resources such as books. Many were orphans, and word spread that they could find safety and sanctuary in Rebecca’s school.

From this rudimentary beginning, Rebecca founded the UNIFAT elementary school (Upper Nile Institute For Appropriate Technology), which now enrolls over 3000 students. Although the level of civil violence has subsided, still today many of the students at UNIFAT are orphans due to ongoing armed conflicts and diseases. Youth service projects from many countries provide financial support for these students.

Sadly, Ms. Odongkara died in July, 2016 at the age of 86.

Chief Joseph Ole Tapinko

Chief Tapinko, the leader of over 5000 Maasai in central Kenya, and his wife Cicilia Seleyian, help westerners understand both the traditions of the Maasai and the challenges that many of the approximately 600,000 Kenyan Maasai face as the combination of drought, grazing restrictions, and modernization threaten their nomadic lifestyle and they increasingly live in more permanent communities. While these offer improved opportunities for formal schooling and better access to health care, other essential survival skills, for example raising livestock and crops, require developing new approaches. Increasingly, young Maasai are torn between traditional and Western cultures.

Part of Chief Tapinko’s goal of bridging these gaps is aided by the Maasai Good Salvage Outreach Organization. This not-for-profit promotes the preservation of many Maasai traditions, but also leads educational campaigns against those cultural practices that are not consistent with good health and human rights.
