" My philosophy of care is centered around patient information and patient understanding. I embody this team concept, which means treatment decisions are made by the collective understanding of the patient and family, primary care physician, and the surgeon. When everyone is on the same page, the patient is empowered and allows for a speedy and more effective recovery.
