Russell D. Yang, M.D., Gastroenterologist  Dr. Yang graduated with  honors from Baylor College of Medicine in 1984, completed residency at Duke University Medical Center and has been in practice for over 34 years. 

Gastroenterology at Ali'i Health Center believe that it’s our mission to care for patient’s health through the early detection of colon, stomach, and esophageal conditions. With conveniently located offices  in the Keauhou Shopping Center patients have favorable access to care in west Hawaii. Ali'i Health Center’s team of specially trained physicians offer preventive care for a variety of gastrointestinal conditions. They can help patients who struggle with gastroesophageal reflux disease (GERD), unexplained abdominal pain, hemorrhoids, diverticulitis, irritable bowel syndrome, and more. Because the team focuses on preventive care and early detection, they often incorporate nutrition counseling into each patient’s care plan. The doctors spend time teaching patients about healthy eating habits and tailor custom eating plans based on each patient’s specific needs. Ali'i Health Center offers flexible scheduling for diagnostic surgeries such as endoscopies and colonoscopies. Dr. Russell Yang is currently accepting new patients. We welcome both new and existing patients to the practice.
