Born and raised on the islands of Greece, Nikolas moved to New York City at the age of 18 to study acting at NYU's Tisch School of the Arts, where he was picked out by Lee Strasberg as one of the most promising actors of his class. Nikolas quickly gained recognition in New York's theater community. Some of his most notable works in the theater included Shakespeare, Chekhov, Brecht, Sophocles and Euripides, in the U.S. and abroad. Recently, Nikolas can be seen on Girls, Blue Bloods, and the Amazon original series Patriot.
