About me

“A pleasant atmosphere, professionalism and the feel-good factor create trust.”

I was born in Graz and initially followed a career as an area manager for a renowned company in three Austrian provinces in the private sector. Late in my career I completed my training and further education at the two medical universities in Graz and Vienna as well as at the Charité in Berlin. Today, I am a specialist in cardiac surgery and – eager for ongoing training – am acquiring the specialty of vascular surgery.

From 2013 to 2021, I worked at the University Clinic for Cardiac Surgery and acquired years of expertise in the field of pacemaker, defibrillation, and resynchronization therapy. In 2021, I received the certificate for pacemaker therapy, which enables me to offer a comprehensive range of pre- and post-operative care for my patients in my office. In addition to my training at the Department of Pediatric Cardiac Surgery, I completed the Diploma in Sports Medicine of the Austrian Medical Association and received the additional qualification as a sports physician.

Most recently, I obtained the title of “Dr. scient. med.” after successfully completing my doctoral studies in applied medical science. 

In addition to pre- and post-operative care in the office, ongoing activity and research at the Department of Cardiovascular Surgery at the Floridsdorf Clinic allow me to provide optimal care to my patients before, during and after surgery. A high degree of interdisciplinary collaboration between clinical departments, as well as highly intensive scientific research in the field, also allow me to provide timely, high-quality treatment to my patients.
