From the opening paragraphs of the article:
Derreck Kayongo is an entrepreneur and the former CEO of the National Center for Civil and Human Rights. He founded the Global Soap Project (now acquired by Clean the World), a humanitarian aid organization for collecting discarded and unused soap from thousands of hotels worldwide, reprocessing it, then distributing it to in-need populations around the world. The organization battled global health issues in 90 countries, and hygiene-related diseases, and the resulting deaths have dissipated in many at-risk communities.
Kayongo will be the closing keynote speaker at the Montessori Event 2020, March 12–15, in Dallas (montessorievent.com). In his talk, “Harnessing Your Power to Create Change,” he will share his visionary ideas about creating an environment in which everyone is empowered to thrive.
His TEDx Talk that will give you a great introduction to him and his special work.
