Past Appointments

Before my current appointments, I held Consultant Cardiac Surgeon positions at St Luke’s Hospital and the Interbalkan European Medical Centre in Thessaloniki, Greece, as well as at St George’s Hospital in London and Liverpool Heart & Chest Hospital in the UK. These roles consolidated my independent consultant practice across complex adult cardiac surgery and service development.

Prior to my consultant posts, I completed a Fellowship in Adult Cardiovascular and Aortic Surgery at Toronto General Hospital, Canada, under the leadership of Professor Tirone E. David. This advanced fellowship provided extensive experience in complex aortic and valve surgery within a high-volume international centre of excellence.

My higher surgical training in Cardiothoracic Surgery was undertaken within the East London Rotation in England, including appointments at the Royal Brompton Hospital, London Chest Hospital, St Bartholomew’s Hospital, and St Mary’s Hospital. During this period, I gained comprehensive experience in adult cardiac surgery, paediatric and congenital cardiac surgery, and thoracic surgery.

Earlier, I completed my junior surgical training in England across several major teaching hospitals, including posts in cardiothoracic surgery, intensive care, accident and emergency, orthopaedics, and general surgery, building a broad and solid surgical foundation.

At the beginning of my medical career, I undertook compulsory military service in Greece as a Surgeon-Ensign in the Hellenic Naval Forces, serving in thoracic and vascular surgery, general surgery and emergency care, including deployment as a ship surgeon.
