Welcome to Cologne

We are pleased that you are interested in the holistic consultation and innovative treatment available by our interdisciplinary group of experts.

Maybe you yourself are suffering from cancer or a relative, friend or acquaintance is affected. There are an immense number of treatments available for cancer, but you always ask yourself the question if all the treatment options have been taken into consideration. 

In the last few years there has been extensive research on immunological therapies for cancer. We want to make these therapies available for our patients in the form of an individual treatment plan. Our practice is centrally located in Cologne, Germany.

Please call us to arrange a personal consultation.
