FMH Specialists  for Gastroenterology 

FMH Specialists for General Internal Medicine

Welcome to our private practice for gastroenterology and hepatology


In our practices in Basel and Aarau, we offer a variety of specialist medical examinations and therapies for gastrointestinal complaints, including liver diseases and inflammatory bowel disease (Crohn's disease, ulcerative colitis). Our goal is the careful and best possible treatment in your personal situation. With a well trained staff we guarantee an individual patient care in a pleasant environment.

We adapt our medical infrastructure to the ongoing development, so that we can treat you with the most modern technology. Due to our constant training you will be accompanied with the latest knowledge and the highest standards.


As a so-called referral practise, we usually support you after a recommendation from your GP or a referral from a specialist. We work closely with them for each decision.


We have spent years building strong relationships with our gastroenterological and surgical colleagues in the region, surrounding hospitals and throughout Switzerland. With our excellent network, we can offer you a wide range of high-class services close to your home.
