Primary Care/Internal Medicine

Primary Care

Alliance Medical Group has experienced, highly-trained primary care/internal medicine physicians (often called internists) who focus on adult medicine. We care for patients for life –from teen years through the end-of-life.  Our physicians have had special training that focuses on the prevention and treatment of adult diseases. At least three of their seven or more years of training are dedicated to learning how to prevent, diagnose and treat diseases that affect adults. Some of our physicians complete additional training to "subspecialize" in one of 13 areas of internal medicine, such as cardiology or geriatrics. Our primary care physicians/internists are often called upon to act as consultants to other physicians to help solve puzzling diagnostic problems.
