About us

For us – as a team – the trusting doctor-patient relationship is an indispensable basis of our work. Therefore, we take time for you, consider you as a whole, individual person – not as a collection of symptoms – and give a lot of space to the consultation. Every patient can expect 100 per cent care and attention from us, regardless of their origin, religion or social status. Only when you not only receive excellent medical care, but also feel comfortable with us, have we fulfilled our claim.

For this purpose, too, we attach importance to ways of dealing that are characterised by friendliness, empathy, respect and openness. This applies to our patients as well as within the practice team. Our culture of communication helps to ensure that all the cogs in the wheel mesh optimally, so that everyone in their respective specialist field contributes to the common goal: to make our patients healthy quickly and gently.

In order to succeed, we rely on a coordinated interplay of personal competence and experience on the one hand and technological support and medical networks on the other. All members of our team therefore undergo continuous training and keep up to date with the latest research. Consistent quality management ensures that potential sources of error are identified and eliminated at an early stage – the maxim here is to get a little better every day. In addition, we use the most modern technologies if they have been proven to bring about an increase in knowledge, chances of healing and/or tolerability. We are also open to alternative procedures that have proven successful in practice, as our acupuncture offer illustrates. And finally, we see ourselves as fair partners of other health care providers, not as competitors; the basis for joint treatment successes across disciplines.

The efficiency of our actions plays a major role for us – because in medicine, efficiency means above all that patients recover faster and with less effort, which is in their best interest. In addition, an efficient use of resources and funds ensures a lower environmental impact and ultimately also lower health insurance premiums. In this way, we also fulfil our social responsibility as a medium-sized company.

Team

All members of our practice team have excellent training and keep their finger on the pulse of medical progress with regular further training. Dr. med. Frank Beekmann and Dr. med. Rainer Ruf have gained not only broad specialist skills but also many years of practical experience at numerous stations.
