our consulting hours from monday till friday

In order to provide you with the best possible care, our consultation hours are appointment-based. If it is an emergency, please refer to the menu sub-item „Emergency consultation/without appointment“.
You have been advised an orthopedic or neurosurgical operation and you would like to have this checked again by another specialist? Or you need a medical expertise?
Please indicate this when you contact us, so that we can process your request quickly and to your satisfaction.
Acute pain and emergencies cannot be planned! Therefore, the ONZ medical team offers emergency consultation hours at all locations.
The emergency consultation takes place daily in all practices from Monday to Friday between 08:00 - 09:00 and 13:00 - 14:00 (in Dortmund 13:30 - 14:30). As our capacities are limited, we kindly ask you to make an appointment by telephone or book an acute appointment in our online calendar.
