Ann Pretorius, together with her late husband, Peter, founded Joint Aid Management (JAM) in 1984. JAM is an African-founded and headquartered, Christian international humanitarian relief and development organisation currently operating in Angola, Mozambique, Rwanda, South Africa, South Sudan, Uganda and Sierra Leone. Since its inception, JAM has progressed as an organisation that reflects strong, expansive development. For more than three decades it has grown into an organisation that affects sustainable change, though providing programmes to children who need support, and communities that need help. Serving Africa is what they do irrespective of race, religion, gender, or political persuasion.
