What We Do

Internal medicine physicians specialize in adult medicine, and are specially trained to solve diagnostic problems, manage severe long-term illnesses, and help patients with multiple, complex chronic conditions. We provide comprehensive, longitudinal patient care. We have life-long relationships with our adult patients. Our patients are more than symptoms and diseases, and our recommendations are based on each patient’s unique situation. Often, other medical professionals call upon Internal Medicine Physicians for our ability to connect the dots, help solve problems, and identify solutions.

What Makes Internal Medicine Unique


Our Career Pathways

Internal medicine physicians have a comprehensive knowledge and expertise in adult health and understand lifestyle and environmental influences and how everything works in unison. We are uniquely qualified to provide comprehensive patient care and often care for patients over the duration of their adult lives. We do this in many ways and in a variety of settings.

Internal medicine physicians are everywhere. We care for patients in outpatient settings (sometimes referred to as “primary care”) and inpatient settings, such as hospitals. Internal medicine physicians known as “hospitalists” focus on caring for patients in a hospital setting. We also care for patients in other clinical settings, such as rehabilitation centers, long-term care facilities, and health clinics.

Some internal medicine physicians go on to take additional training to "subspecialize" in more focused areas of internal medicine. After we complete this training, we are frequently referred to by this area of subspecialty focus. For example, those who subspecialize in diseases of the heart are usually called “Cardiologists.” Regardless of these subspecialties, we are all internal medicine physicians first, and share the same foundational internal medicine training.

Internal Medicine is a launchpad for many different career pathways and a gateway to health care leadership and impact. In addition to providing longitudinal patient care, conducting research, and leading teams in clinical environments, Internal Medicine Physicians thrive in leadership roles at hospitals and health care systems, and in business, technology, and public policy.

…There is so much that I love about outpatient general medicine: meaningful longitudinal relationships with patients over time; history taking, physical exams, and engaging in clinical reasoning to determine next steps; thinking holistically about patients; and focusing not just on disease treatment but also disease prevention and maintenance of health.
