Curriculum Vitae

Medicine has never been just a profession for me—it has always been an inner calling. From an early age, I was deeply moved by the way knowledge, technology, and genuine care can change lives. Today, as a Gastroenterologist and Senior Registrar at “G. Gennimatas” General Hospital, I continue to serve that vision.

My career includes a PhD at the National and Kapodistrian University of Athens, focused on cellular prognosis in colorectal cancer, as well as training in advanced interventional techniques such as ERCP and EMR. Despite my scientific achievements, I believe that what truly matters is the way you stand beside your patient.

Through publications, conferences, and collaborations, I consistently set the bar high. My goal is to transform worry into certainty, and the unknown into a clear, personalized plan of care. Beyond medicine, I am a husband and father of two children—my family reminds me every day that health is the most valuable asset we have.

For me, every patient is unique and deserves care grounded in respect, precision, and humanity.
