Born in Filiatra Messinia. Studied in Kostis Michailidis Theatre School and Veakis Theatre School, in Athens.

Taking example from Socrates - the original "gadfly" - Nikos Kaloyeropoulos has devoted his life's work to the unsettling of modern Greek society and its conceptions on how life should be lived and ruled. In addition to being a multi-awarded actor he is a playwright, composer, lyricist, poet and prosaist.

In "Riders of Pylos", his first feature film, he summons values and examples from all stages of Greek history, and approaches storytelling with an air of freedom consistent to his main character's values.

His awards include two Greek State Awards for Best Actor in a leading role and one for Best Actor in a supporting role as well as the prestigious Greek State Award for Exceptional Performance for his lead in "Rembetiko" by Kostas Ferris.
