Médecins Sans Frontières (MSF) is an international humanitarian aid organisation that provides emergency medical assistance to populations in danger in more than 80 countries. In countries where health structures are insufficient or even non-existent, MSF collaborates with authorities such as the Ministry of Health to provide assistance. MSF works in rehabilitation of hospitals and dispensaries, vaccination programmes and water and sanitation projects. MSF also works in remote health care centres, slum areas and provides training of local personnel. All this is done with the objective of rebuilding health structures to acceptable levels.

In 1990 Médecins Sans Frontières Greece was founded as an association. Since then the organization has provided medical assistance to more than 40 countries with the participation of 450 volunteers. 

MSF Greece is supported by 136.000 private donors who make possible the operation of humanitarian programs. In the last 15 years, programs have been developed in Africa, countries of the ex-Soviet Union, Asia, and the Balkans. Today, MSF Greece has programs in Greece, Zambia, Liberia, Syria and Niger.
