Leadership team

Marianne Kent-Stoll - Co-Founder and President

19 - Who we are - Leadership - Marianne.jpg
Marianne Kent-Stoll had dreamed of going to Africa since she was eight years old, when she saw the film Born Free, set in Kenya. In 2007, after the last of her four children went away to college, her dream came true when she and her husband Don visited the Tanzanian village of Dareda Kati. She never imagined that she and Don would return to the village every year for the next decade to work with its people to build a better future.

In addition to serving as President of Karimu, Marianne is Assistant Head of Idyllwild Arts Academy, in Southern California, where more than half of the students are international. Her 35 years in education, her appreciation of cultural diversity, her leadership skills, and a love of Africa that grows deeper with every visit inform her work in Dareda Kati, where she hopes to be able to spend several months every year once she retires from Idyllwild Arts.

Don Stoll - Co-Founder and Treasurer

Don Stoll, who holds a Ph.D. in Philosophy from The Pennsylvania State University, enjoys the good fortune of living fifty yards from his office in the Admissions building of Idyllwild Arts Academy (IAA), in Southern California, where he and Marianne live in a house on campus. He takes great joy in his Admissions work, which focuses on bringing artistically gifted international students to IAA. Although some three dozen countries are represented this year, he is still searching for IAA’s first Tanzanian student. Don has been Karimu’s Treasurer from the day of its founding because he admits to a talent for the sufferance of tedium and to a somewhat peculiar obsession with mathematical precision. With Marianne, he has co-led each of Karimu’s annual visits to Tanzania except in 2015 and 2017, when concerns about the health of some members of his family in California kept him at home.

Both Sifaeli and his wife belong to the Meru tribe, whose homeland lies near Mt. Kilimanjaro, nearly a hundred miles east of Dareda Kati. Yet they have called Dareda Kati home for some 20 years, ever since his encyclopedic knowledge of Tanzanian agriculture earned him a job as supervisor of the farm that was designed to support the Lutheran Diocese of Arusha’s new Integrated Agricultural Training Center, built in one of Dareda Kati’s most fertile valleys. During the annual Karimu visit to Dareda Kati, Sifaeli’s devotion to improving life in the village and his formidable skill as a translator make him the Karimu volunteers’ constant and indispensable companion. Since April 2018, Kaaya has been a board member of Karimu Heart and Spirit Organization in Tanzania.
