Physician Bio

As a family physician, the most rewarding aspect of my practice is helping families to grow and thrive. I often see several people from different generations of the same family. I view the relationship with each patient as a partnership toward better health and believe in treating the whole person—mind and body. I’m passionate about caring for families—from pediatrics and well-woman care to geriatrics—whether they have a common health issue or a serious chronic condition. It’s a joy to help them achieve and maintain good health.
