Specialist in Endocrinology and Diabetology, FMH
Specialist in General Internal Medicine FMH
"One of the reasons I chose endocrinology is the central role that hormones and metabolism play in our health, often long before symptoms appear. Many hormonal and metabolic conditions develop gradually over years. Detecting them early can make a decisive difference in preventing disease and preserving quality of life in the long term.
It is important to me to combine thorough diagnostics with evidence-based prevention and individually tailored treatment. Whether caring for patients with an existing hormonal condition or identifying risk factors at an early stage, my focus is always on holistic, long-term care.
I look forward to bringing this philosophy to the Center for Proactive Medicine and supporting my patients not only in the treatment of endocrinological conditions, but also in maintaining their health and quality of life over the long term."
