MAZA’s mission is to provide transportation for urgent health care needs in remote areas of Ghana that is safe, accessible, affordable, and reliable, while also creating income-generating opportunities for drivers, traders, and farmers. Through a network of multipurpose motorized tricycles and drivers at the community level that is powered by mobile technology, MAZA enables rural families to access health care in a timely manner during an urgent health crisis so that their chances of survival are improved. MAZA works in close collaboration with rural communities, local governments, the Ghana Health Service, and the Ghana Ambulance Service to achieve its aims.
