All my questions were answered. I was able to ask everything I wanted to. It was a friendly conversation and I felt understood and that I was met where I was.

Jan S.10 October 2025

Hi, getting in touch was easy, convenient and reliable. The phone appointment was on time to the minute. The conversation started pleasantly and continued in the same way. I was listened to, I was thanked most politely and there was lots of important information and answers, e.g. the note about the cooperation with health insurers, which cover a major part of the treatment costs. Many thanks for the nice and informative phone call. I have decided to go ahead with treatment.

Ms Zitier gave me comprehensive advice, so the decision to take the next step follows quickly.

Carsten28 February 2026

The conversation with my adviser went very well. My questions were explained in a way I could really understand. She took a lot of time for me. I left the conversation very satisfied and reassured.

Andreas7 February 2026

The first contact via the telephone consultation with Birgit was absolutely positive. The conversation was very informative, all questions could be discussed and answered, and on top of that I received a lot of additional information and explanations. The whole atmosphere of the conversation was incredibly friendly, and at no point did I feel there was any time pressure or that I was supposed to be ‘talked into’ something. My conclusion is that after the conversation I feel better advised than I had expected beforehand. Thank you very much for that

Susanne14 January 2026

Today I had a consultation. I was asked personal questions about my medical history that are significant to me and will be very important for the upcoming treatment. They listened carefully to what I had to say about my background. I was also given precise information about my personal costs / coverage of costs by the health insurer or financing. The consultation was very informative for me, and the conversation overall was very pleasant and very friendly.
