NGO Symplefsi organizes, on an annual basis, the crossing of the Aegean Sea during which the team stops on isolated islands. Symplefsi offers donations of supplies and equipment for schools, free diagnostic tests by doctors and nurses of all specialties, infrastructure ( i.e. desalinators, multipurpose courts, playgrounds etc.) as well as other donations related to education, culture, sports and the environment. The ultimate objective of Symplefsis remains, throughout the years, the strengthening and improvement of living conditions for the residents of the remote islands of Greece.
