Mission statement

For us as a team, a trusting doctor-patient relationship is an indispensible foundation for our work. That is why we take time for you, see you as a whole, individual person – not just a collection of symptoms – and place great importance on consultation. Every patient, regardless of descent, religion or social postion, can expect our 100% attention and care. Not until you not only feel you have received excellent medical care, but when you also feel comfortable, have we lived up to our mission statement...

Healthy air doesn't need open windows

You might be surprised that all windows in our practice rooms are closed - even in summer and during pandemic times. The reason lies in our special air conditioning system: It not only ensures pleasant temperatures, but also filters pollutants and pathogens such as viruses and bacteria from the practice air.mehr
