Claudia Lippuner

Nadine Hollenstein


Since November 2021 I am part of the DocDavos team as MPA. I grew up in Davos Wiesen. I completed my apprenticeship as an MPA in Davos in 2019. In my free time I can often be found in nature or with friends in a café.

Andrea Toggwiler


I grew up in Schiers and attended primary and secondary school there. I completed my apprenticeship as MPA EFZ at the MPA vocational school in Buchs in 2016 and have been part of the team ever since. In my free time, I like to go snowboarding, swimming and to watch HCD games. 


Gregor Niedermaier

Dr. med.


Since 2010 I have been working as a resident family doctor in Davos. In my free time, I enjoy mountain biking, swimming in the Davos lake or cross-country skiing. As an inactive pilot, I am also interested in flying in general. But I also appreciate city trips, ice hockey and playing the clarinet. 


Ruth Niedermaier

Practice Manager

Since 2010, I have been running the family practice in Davos together with my husband Gregor as a practice manager.

Besides my son, my interests include traveling, reading, baking, knitting, skating and ice hockey. 


Teresa Thieke

Dr. med.


As the newest member, I joined the team in January 2020 after previously working in St. Gallen.  I like to spend my free time with my family. My hobbies include traveling, cross-country skiing, road biking, and swimming. But I also enjoy oil painting and creative work of all kinds. 

High up here, man loses his last remnant of sanity because of all the happiness and panorama. People put wood under their feet and rush down to the valley. When you arrive at the bottom you either go to the hotel or to the doctor.
