While holidaying in a rural area in France, we had a video consultation with Dr. Joshua Nießen. Despite our weak signal, he stayed on the call and ensured everything was sorted. He provided a thorough, professional service, and the appointment, care, and aftercare were excellent. Highly recommend.

We were a bit concerned about my health sitting on the middle of the Rhine.. We are 70 year old Australians on the holiday of a lifetime. Dr Nieben was able to calm us down and provide the health services that we required. It was a bit difficult finding a Chemist in close proximity to one of our stops on our River cruise but Dr Nieben was able to help us with that as well
