Physician Bio

My professional approach includes preventive care, patient education, and individual treatment planning based on the latest achievements in medicine. I encourage patients to actively participate in their own treatment selection process.

It is important to take the time to discuss problems with a patient, so we can work together toward a mutually agreeable decision.

Family tradition.

listening to classical music, reading biography and popular science books, and playing tennis.
