I am a Board Certified Internal Medicine Physician trained at the Cleveland Clinic. After 20 years with the San Jose Medical Group, I moved my practice, in March 2015, to the Samaritan Internal Medicine Group, part of Stanford Healthcare. What is an internist or physician in Internal Medicine? I like to explain in like this: You know how Pediatricians are specialists with children, well, Internal Medicine is a specialty for adults. We do not do surgery, we do not treat children, we do not deliver babies. But we have a more in-depth knowledge of adults and the subspecialties of Internal Medicine: Cardiology, Gastroenterology, Rheumatology, Endocrinology, Hematology, Pulmonary And Hospital Medicine than a General Practitioner or Family Medicine physician.
