Thomas “Tom” Michael Koulianos passed away peacefully on January 15, 2026. He was a devoted father, grandfather, and great-grandfather; a public servant; and a trusted professional whose life was defined by integrity, service, and unwavering dedication to his family and community.

Tom is survived by his beloved significant other, Doreen Fiorella, and his four children: Michael Koulianos of Washington, Illinois; Foti (Rose) Koulianos of Tarpon Springs, Florida; Kollet (John) Barkhouse of Tampa, Florida; and Annie (Cory) Blanchard of Valparaiso, Indiana.

He was a loving grandfather to thirteen grandchildren: Thomas Koulianos, Denise Backes, Nicholas Koulianos, Alexandria Kareotes, Katina Guzlas, Christopher Koulianos, Alexandra Koulianos, Connor Barkhouse, Ava Koulianos, Claire Koulianos, Jack Blanchard, Erin Koulianos, and Melanie Blanchard.

Tom was also blessed with five great-grandchildren: Marina Koulianos, Michael Koulianos, William Backes, Nikolas Backes, and Olivia Guzlas.

He is also survived by his siblings, John Koulianos, Theo Koulianos, and Helen Jones.

Tom was preceded in death by his parents, Michael and Anna Koulianos, and by his brother, George Koulianos.

As Mayor of Tarpon Springs, Tom served his city with humility and purpose, guided by a deep belief in civic duty and community involvement. His leadership left a lasting impact, and he remained a familiar and caring presence long after his time in office. He was equally proud of his work as a Certified Public Accountant, where he served his clients with professionalism, trust, and care.

Tom will be remembered for his wisdom, humor, and steadfast devotion to those he loved. He was deeply loved by many, including countless nieces, nephews, extended family members, friends, colleagues, and members of the Tarpon Springs community and beyond.

His legacy lives on through the family he cherished, the community he served, and the many lives he touched.
