Board Certified Gastroenterologists in Anchorage, Alaska

Gastroenterology is a branch of medicine that focuses on the digestive system and its disorders.  Alaska Digestive and Liver Disease provides specialized medical care to patients with disorders of the digestive tract, including irritable bowel syndrome, inflammatory bowel syndrome, peptic ulcer disease, diseases of the liver, bile duct and pancreas, and more.

The Anchorage office space is shared by two board certified gastroenterologists, Dr. Ronald J. Boisen, M.D., and Dr. Daryl M. McClendon, M.D.  They are both Fellows of the American College of Gastroenterology.  Fellows are a special group of dedicated doctors who have received an honorary designation to recognize their ongoing education, service, and contributions to the practice of medicine.  Gastroenterology fellowships are 3 year programs which provide further training in endoscopic procedures and digestive disorders.  Fellowships are completed after medical school and a residency.

  • "From my first phone call to his office and subsequent video conferencing with Dr. McClendon did I realize that I had got the right Doctor. My interaction with his staff and him were amazing. For a person that is anxious and reluctant to go to doctors, they made me feel at ease."
