PTPG pathologists have spent at least five years beyond medical school specializing in the study of all manner and types of disease. We are involved in caring for you by consulting with you and more often your physician. In many cases, you may never see us. That’s because we often work directly with your doctor to provide additional expertise as needed.
Whether your PTPG pathologist focuses on the study of your tissue and cells (anatomic pathology) or your blood and other body fluids (clinical pathology), you can be assured that he/she acts as a behind-the-scenes guardian of your health.
