Sotiris Sorogas was born in Athens in 1936. He studied painting at the Athens School of Fine Arts with a scholarship from the Greek State Scholarship Foundation (1957-1961), under Y. Moralis. He also attended the ASFA iconography workshop from 1962 to learn about Byzantine painting, which had always interested him. His first solo exhibition was presented in Athens in 1972 (Athens Art Gallery – Hilton), and in the same year, he received an annual grant from the Ford Foundation.

His early works showed an affinity with the politicized photorealistic trends of the dictatorship era (use of black-and-white photographs, splashes of red, etc.). Soon, however, his personal themes took shape, focusing on a poetic approach to time and decay. His painting is characterised by precision of drawing in compositions that are often monochrome and fragmentary, where lyrical narrative elements are developed through the dialogue between objects and space. The thematic series he has presented (Horses, Black Openings, Female Portraits, Old Woods, Scrap Metal, etc.) refer to human or historical memory through images that combine sensitive observation with structural perfection.

He was a founding member of the Association of Contemporary Art and the Society for the Study of Greek Culture (2010). He also participated in the Group for Communication and Education in Art and in the editorial board of the art theory magazine "Spira." He was elected professor at the School of Architecture of the National Technical University of Athens (1964-2003). He represented Greece at the São Paulo Biennale (1981). He participated in Europalia (Belgium, 1982) and the 21st International Painting Festival (Cagnes-sur-Mer, France). He was awarded by the Academy of Athens for his overall artistic contribution (2004). Retrospective exhibitions of his work were organized in 2010 at the Cultural Organization of the Municipality of Trikala - the Makris Foundation, and in 2011 at the Benaki Museum. Six of his large compositions have been installed at the Larissa Station of the Athens Metro (2010). Studies, articles, reviews, and three monographs have been written about his painting.

He lives and works in Athens.
