The Department of Medicine at Loma Linda University Health helps adult patients — both sick and healthy — be healthier. Our goal is always to heal the body, the mind and the spirit.

Whether it’s an illness, an injury or just preventive care, our internal medicine physicians, or internists, provide innovative, comprehensive services. We're here to serve you both in clinics for brief visits and for longer stays in the hospital. If we don’t have the tools to make you feel better, we can refer you to an in-house specialist who does.
