“My favorite aspect of practicing Family Medicine is the opportunity to listen to my patients’ concerns and health stories to help them achieve optimal well-being. I enjoy partnering with my patients to provide a continuity of care that is comprehensive and patient-focused. I also coordinate care with other specialists as needed to ensure that the individualized needs of my patients can be met.”
