Career of Dr. medic Stergios Chantzaras
Specialist in Internal Medicine and Cardiology
My medical career began with a degree in human medicine at Victor Babeș University, which I completed in 2013. After receiving my medical license in 2014, I first gained broad experience in internal medicine at St. Vincenz Hospital in Datteln, before shifting my professional focus to cardiology in Düsseldorf.
At the Evangelical Hospital Düsseldorf (EVK), I worked for many years in the Department of Cardiology – initially as part of my training in internal medicine and cardiology, and later as a specialist. During this time, I obtained my specialist qualification in Internal Medicine (2021), the additional qualification in Intensive Care Medicine (2023), and my specialist qualification in Internal Medicine and Cardiology (2024), each awarded by the Ärztekammer Nordrhein (North Rhine Medical Association).
Today, I combine my many years of clinical experience with individual, holistic care for my patients. It is especially important to me to explain medical matters in an understandable way and to find the right treatment together with each patient.
