Internal medicine doctors you can trust

Many adults choose an internal medicine (IM) physician as their primary care physician (PCP). Internal medicine doctors are equipped to deal with any problem a patient brings: common or rare, simple or complex, one or many. Internists strive to educate their patients on wellness; their focus is on the care for the whole person, not just the illness.

ARC internist team

An internist is a PCP who cares for their patients during all stages of adulthood (over 18 years). When other medical specialists are involved, an internist will coordinate their patient's care. If you have a condition that requires a doctor’s attention more than twice a year, it’s probably time to establish care with an IM doctor.

Internists routinely see patients with heart disease, hypertension, diabetes, obesity, and chronic lung disease. Internists are trained in subspecialty areas of internal medicine, including rheumatology, gastroenterology, cardiology, nephrology, infectious disease, neurology, pulmonary medicine, critical care, endocrinology, and allergy.
