In 1902 he was appointed as a teacher to Serres and Alexandroupoli, where he got involved with the Macedonian Committee and became an active member of the Macedonian Struggle. Later, he served as a teacher in the Phanar Greek Orthodox College, the "Joachimio Greek Girls' School of Constantinople" and in Thessaloniki. He was also a member of the "Greek Philological Society of Constantinople" ("Ελληνικός Φιλολογικός Σύλλογος") and contributed as a judge and rapporteur in literary and folklore competitions of the philological magazine of the Society. At the same time, he developed nationalistic actions, as in 1912 he organized the first congress of teachers of the enslaved Hellenism of Asia Minor and attended a "Great National Assembly", thus being expelled and imprisoned by the Ottoman authorities.
