St. Luke's Clinic – Internal Medicine: Mountain Home

We’re a team of trained and experienced healthcare professionals skilled in medical care for adults, including routine and preventive health checks, diagnosis and treatment when a medical problem is first suspected, and ongoing management of chronic illness. As internists, we keep the whole patient in mind, rather than merely focusing on a single disease or organ system. 

We offer a broad scope of services, including (but not limited to) the diagnosis and treatment of heart disease and hypertension, kidney disease, gastrointestinal problems, allergies, cancer, anemia, and lung problems, such as asthma and emphysema. We also manage infections, neurological problems, such as strokes and seizures, nutritional problems, depression, skin disease, and diabetes and thyroid disease.
