Born and raised in Southwestern Ontario, Canada, Leslie earned her Degree in Psychology and Early Childhood from the University of Waterloo. She then went on to earn her Teaching Degree at York University. As an experienced educator, with many years in leadership, Leslie devotes much of her time and energy at Tumaini through her Minds On Learning Venture, providing educational support and learning pedagogy to schools and teachers near Usa River. Leslie is the very proud mom of two grown children. Leslie Butler first travelled to Tumaini in 2017 for what she knew would be a life changing experience. She returned again in 2019, with plans to return regularly to the children and adults she has grown to love, respect and appreciate.

Having always had a passion for facilitating excellence in youth and an interest in Africa, Tumaini was an easy fit for Leslie. Leslie continues to support Tumaini by participating in ongoing educational growth ventures, in guidance and care for Tumaini children and in supporting the many fundraising requirements needed to run the foundation.
