Dr. Paul-Georg Behler brings specialist expertise in internal medicine and pulmonology to the family practice context. His deep understanding of sleep medicine is especially relevant for families – sleep disorders in parents affect children, and vice versa.

Our Philosophy

Family medicine that goes deeper.

Four principles that guide how we care for every member of your family – at every stage of life.

The whole family

We treat children and adults together. Understanding one generation’s health history helps us care better for the next – and prevents conditions before they arise.

Time to listen

Good family medicine requires unhurried consultations. We build in the time to listen, to ask, and to understand – for children and adults alike.

Prevention for life

We believe the best medicine is the medicine you never need. We invest in prevention at every age – from developmental screenings in children to early detection in adults.

One trusted practice

No need for multiple practices, multiple registrations, multiple waiting rooms. Your family has one home – where everyone is known, and where continuity of care is the standard.

Medical responsibility

Personal care with continuity

Dr. medic Diana Mihaela Behler and Dr. med. Paul-Georg Behler combine general medicine, nutritional medicine and internal medical expertise. The family practice aims to provide understandable guidance and coordinated medical support for children, parents and adults.
