He arrived in Greece in 1900-1901 and begun as a professor at the Dramatic School what was then Royal Theatre and (after the separation of Angelos Vlahos) as a director.
He knew the young Marika Kotopouli who he acted together in an erotic part and became a protagonist of that company.
His luck was crowned by the critics and a loud noise at failed receipts that made Oikonomou in theatrical productions and his works to collapse.
His contribution at the Greek theatre as a director and a hypocrite as well as mainly from the student's spot thought he was fixed.
