Lekoko Ole Sululu
Co-Founder, National Director

Lekoko Ole Sululu co-founded Terrawatu and has served as the organization’s co-director since 2001. Sululu was born in a traditional Maasai village in the Ngorongoro Conservation Area in Tanzania and spent his childhood herding his father’s cattle, being initiated as a warrior, and learning the medicinal plants and sacred rituals of the Maasai. For over 20 years, he worked as a guide on Mt. Kilimanjaro and for wildlife safaris with several prestigious travel companies based in Tanzania and the United States before co-founding Terrawatu with Dr. Tanya Pergola. A respected Maasai elder, Sululu is a traditional healer and herbalist and is the director of the People-to-People Safari Company. His primary home is in Arusha, Tanzania and he travels extensively throughout Maasailand advising communities on how to maintain their traditional culture while developing in new and sustainable ways.
