He studied electric guitar, jazz Harmony, as well as upper level classic theory (harmony, counterpoint, fugue) in Athens at FILLIPOS NAKAS Conservatory and in Amsterdam, Holland at CONSERVATORIUM VAN AMSTERDAM. After completing his studies, he began to teach guitar in the modern department of FILLIPOS NAKAS, where he works until today, while YAMAHA recently chose him to teach one of its musical programs, YAMAHA POPULAR MUSIC.
