Back to about usMy Journey
From Heidelberg to Hamm – my medical path
After my summa cum laude studies in Heidelberg and positions at the university hospitals in Düsseldorf and Bochum, I now practice in Hamm. My extensive experience as a senior physician in intensive and emergency medicine, along with my research on cardiovascular diseases, forms the foundation of my current practice.
In Hamm-Heessen, I offer you medicine at the highest clinical level, combined with personal and empathetic care – even in critical moments.
