Field of expertise
Physician / Osteologist-DVO
Senior Clinical Research Physician
Twenty-five years of clinical research and patient care at leading university institutions in Germany, Canada, and Switzerland have given me a wealth of osteological expertise that I am eager to share with my colleagues at the Center for Proactive Medicine — and through them, with our patients.
"Best Research – Best Medicine – Best Patient Care" was the motto of Mt. Sinai Hospital in Toronto, displayed prominently above the main entrance. For me, it has always been a personal standard as well.
Over the past 10 years, I have successfully applied my experience — and developed new ideas for better patient care — not only within academic medicine, but also at other locations in Germany and Switzerland.
It has also been an honor to serve as Senior Medical Advisor for the International Osteoporosis Foundation (IOF), based in Nyon (CH/VD).
In this spirit, I look forward to continuing to live these values at the Center for Proactive Medicine on Rennweg in the heart of Zurich — as an advisor to a dedicated interdisciplinary team committed not only to the treatment, but also to the early detection and prevention of osteoporosis.
