Joy Sun

Joy is Co-Founder of Groups, a venture-backed healthcare services company that provides affordable, evidence-based treatment for heroin and opioid addiction. Groups operates primarily in rural communities that have been hardest hit by the opioid epidemic, yet have the least access to high-quality treatment. Previously Joy served as GiveDirectly's Domestic Chief Operating Officer, where she helped to make cash transfers a new benchmark for efficiency, transparency, and impact in giving and international aid. She was a manager at McKinsey & Company and served clients in the healthcare and agriculture sectors. She has also served as Director of Operations at the Clinton Health Access Initiative, where she launched several field operations across Africa, including Lesotho, Swaziland, and Nigeria, and helped lead the organization's growth from a start-up into a global institution. Joy holds an MBA from Stanford's Graduate School of Business and a BS from Georgetown's School of Foreign Service.
