A top qualified team awaits you

Nephro am See was founded by two physicians with many years of experience: Nephrologist and Internist Sen. Lect. Jan Bruegger, M.D. (Head Physician) and Dr. med. dent. Lea Bruegger (Managing Director).

They founded Paramecium AG in 2019 with the aim of establishing a centre for kidney treatment and dialysis in the Horgen region, close to Zurich.

«Our focus is always on the patient. We guarantee maximum safety and provide the highest quality medical services. We believe in appreciative and respectful treatment - not only of our patients but also within our team. Our employees distinguish themselves through their empathy and many years of experience.»
