Giannis Efthimiou studied for three years at the School of Marble Sculpture in Tinos, where he came in contact with the art of marble and sculpture. This study played a decisive role in the development of his painting, while during his studies (at P.E.S.K.T.P.T) he received an honorary distinction in sculpture and painting. In 2011 he entered the School of Fine Arts at the First Painting Laboratory, where he excelled, and graduated in 2017. In the same year he won the “Spyropoulos award”, while in 2018 in the National Insurance competition he was awarded the second prize. His first solo painting exhibition took place in June 2020 at the Evripides Art Gallery.
