William is an Analyst on the Consulting team at EFCG. He recently graduated from Harvard University with a B.A. in Computer Science. During his studies, he worked in the non-profit sector which has enabled him to think more strategically about how business decisions affect our communities, and how these decisions can be curated to ensure mutually beneficial outcomes for businesses and the communities they serve. He also completed an internship program that focused on the knowledge that exists between small and medium businesses in southern Africa. William is an avid runner and enjoys skydiving, travelling, and learning about different cultures. Originally from Botswana, but currently living in the Boston area, he hopes to one day find a local sports team to support.
