Jason Leiser



Jason is an attorney with a love for anthropology and education. He co-founded One Pencil after working with the Tsimane in Mision Fatima, Bolivia. Jason realized that short term support for local goals and projects would not create long term solutions. Jason has overseen all legal aspects of One Pencil. And in addition to his diligent works behind the scenes, he also advocates and fundraises in the US. Jason currently oversees the Bolivia chapter.
