Growing up in a small village in southern Ghana, seeing family and neighbors struggle to access basic health care, Osei Boateng decided he would make it his life's mission to bring health care to remote communities in Ghana. He started OKB Hope Foundation, and in 2021, converted a van into a mobile doctor's office which travels several times a week to remote communities to provide free routine medical care. The Hope Health Van has served more than 4,000 Ghanaians across more than 45 rural communities, while 20 volunteers trained as local health advocates have helped more than 1,000 people. Last year, he and his organization launched an initiative to integrate mental health into their care and destigmatize getting help. Boateng, a CNN Hero, thinks his model can be used across Sub-Saharan Africa.
