  • For us, *Dr. Jonathan talk too fast. Hardly to understand. We keep asking to repeat. When I called to make an appointment, I only mentioned 1 issue then when I visited dr. I mentioned 3 issue. He obviously was not happy. *

    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.
