Costas obtained his Master's in Counseling Psychology in the US in 1989. After working with abused adolescents for several years in Texas, he eventually relocated back to his hometown, Limassol, as a school counselor, still in the notion that he would make a difference 'one kid at a time.' However, working in a school setting gave him a better perspective when it became apparent that contemporary classrooms had remained just as passive, crowded, and indifferent to student needs and abilities as during his own student days. Thus, he embarked upon an incredible odyssey to rescue education from schools; full of sirens, cyclops, and blind, Byzantine bureaucracy!

After co-founding the Lighthouse in 2011, besides working on building their new campus for primary and secondary education, he is currently 'all-in' on reconceptualizing the educational paradigm so that it is a proactive partnership with students, AI agency, open-source, engaging, and deeply evolutionary.
