Costas Yannopoulos was born in Athens, Greece, in 1952.
He obtained his Degree in Marketing from Birkbeck, University of London, and upon his return to Greece, he developed two companies in the fields of Informatics and office mechanical equipment.
When his younger son Andreas, aged 10, was diagnosed with cancer in 1995, he left his business in order to help his son fight this battle for his life and make his wish come true. Sensitive and caring, Andreas dreamed of an organization whose mission would be to support all children in Greece and all over the world who may be in danger or have any need. He believed that every child deserved a smile, and this is the reason why he named this organization "The Smile of the Child".
Thanks to the offers, donations and support of Greece’s business world, people and society as a whole, "The Smile of the Child" has now completed 28 years of continuous presence in Greece and has become a point of reference for every child, parent, public worker and government agency as it has succeeded in implementing a wide spectrum of efficient, direct and flexible initiatives in order to provide services to and protect children and families at risk, in the critical areas of Violence, Health, Missing and Poverty.
Aiming to increase its effectiveness, develop expertise and exchange good practices in the field,“The Smile of the Child” participates in International Organizations and Networks for the protection of children's rights, cooperates with important institutions abroad and implements a series of programs in various fields related to the protection of children's rights.
Among others, Costas Yannopoulos is the President of the Board of Directors of the European Antibullying Network (EAN) continuously since 2012, while he also served as member of the BoD of the International Centre for Missing and Exploited Children (ICMEC) for several years.
In 2014 he was awarded the European Citizen's Prize by the European Parliament for the outstanding contribution of “The Smile of the Child” to the protection of children’s rights.
In 2021 he was awarded an Honorary Doctorate at the Department of Education and Social Work of the University of Patras by the same Department, in honor of his 27 years of uninterrupted and substantial contribution to any child in need or at risk.
