Dr. med. Bernd Seitz

Founder, partner and expert

In my specialist practice for holistic, biological, functional and clinical environmental medicine, the health and well-being of people is my central concern. After intensive research into the causes, I provide individualised, targeted and holistic treatment. I use various proven methods from classical university and extended complementary medicine. In addition to recovery, I am particularly concerned with the prevention of illness.

Founder, partner and expert

The basis of my work is the consideration of the human being as a whole, a sound medical knowledge and a detailed diagnosis!

I do not see my work as a naturopath in Menden as opposition or controversy to conventional medicine, but as a complement and extension. The combination of proven naturopathic and modern medical diagnostic and therapeutic methods in particular offers a wide range of possibilities for getting to the root of existing illnesses and not just treating symptoms.

The holistic cellular, biophysical, psychological and social approach is required to successfully treat patients.

Biologically to the optimisation of vital intercellular communication and toxin elimination, psychologically with the processing of unresolved emotional conflicts and socially as a practice with solutions for people with seemingly unsolvable health problems.
