As an Internal Medicine practice, we treat patients 16 years of age and older for any of their medical conditions. Internists are trained to diagnose and treat severe, chronic illnesses. They also help patients understand preventive medicines, men's and women's health issues, as well as common problems of the eyes, ears, skin, nervous system and reproductive organs. Most older adults in the United States see internists as their primary medical practitioners.
