Ion worked under different capacities in "Zygos" arts magazine and at
Galerie Zygos. Upon finishing his military service, which in Greece is compulsory for men, as an NCO Interpreter/Translator for the Greek Armour Officers Academy (1979-1981), he published and edited "Zygos Annual Edition on the Hellenic Fine Arts" (1982-1985).
In 1984, he was asked to contribute "A Brief Survey of Art Publications in Greece" in the Bulletin of the Archives and Documentation Centers for Modern and Contemporary Art (I/1984) published under the Auspices of the International Association of Art Critics.
In 1985 Ion moved to the U.S. and, representing Zygos, he launched and directed Zygos Gallery in Washington D.C. (1985-1991). He was appointed Executive Director of the Society for the Preservation of the Greek Heritage (SPGH), with headquarters in Washington, DC (1991), and later moved to the West Coast and launched and directed Stoa Gallery, in Northern California (1995-1997).
He founded and directed publishing and marketing company Ionic Concepts, CA (1992-1999), served as a consultant to the Hellenic Journal, CA, and
Hellenic Pilgrimage, NY, as well as a consultant to the Hellenic Dimension
Project , Chicago, IL. He served as President of the Lookout Sculpture Park West, and in the boards of the Petaluma Downtown Association, the Cyprus Museum of North Carolina, and others.
In 2000 he repatriated to his native Athens and re-opened Galerie Zygos
which had temporarily ceased operations due to his parents’ retirement. As of April 2009, Galerie Zygos has suspended its exhibition schedule and is operating as an art dealership, sans space, until further notice.
Over the last few years, and aside from his involvement with the zygos4art.com legacy website, Ion is heavily involved with the publishing and the administration of athenskey.com, a website in English about his hometown Athens, designed to be a travel companion, on travel, hotel, villa and home rental accommodation, cruises, yachting and sailing, excursions around Athens, archaeological sites and sightseeing, museums, events, what to do, what to see, where to shop from, when in Athens.
