Public health physician graduated from Alexandria University, Dr. Youssef Naguib first practiced medicine in his native Egypt, then in various other countries. He then joined the international cooperation sector, as a technical assistant for the Belgian Cooperation in Niger, and with Caritas NGO in Alexandria. He joined Samusocial International at the opening of his office in Cairo in 2008 to set up an intervention for children and young people living in the street.
