Physician Bio

As an Internal Medicine and Pediatrics physician, I believe the best foundation of good health care is evidence-based practice, continuity of care, and patient empathy. Maintaing good relations with colleagues is also of vital importance, thus emphasizing the need for frequent and clear communication.
