Johanniter International (JOIN) is the partnership of the four protestant Orders of St John and their national charities. Their member organisations are based in Europe and the Middle East. In close cooperation and supported by more than 100,000 volunteers, they serve humanity with medical services and first aid, social care, international aid, disaster relief and youth work. The services of their member organisations are open to everyone. The central office in Brussels advocates the interest of the St John charities towards European and international bodies and facilitates international projects and working groups.
