About me

I am an experienced endoscopist and perform around 3,500 gastroscopies and colonoscopies per year. My patients also consult me ​​to clarify symptoms of the digestive tract or increased liver values. I am also available at any time for second opinions in the case of stomach, intestinal or liver diseases that have already been diagnosed. I take on the coordination of complex interdisciplinary care for cancer.

My attentive listening, careful review of findings, understandable emphatic communication and my excellent, interdisciplinary medical network are particularly valued.
