Son T. Do, MD

Dr. Do is board-certified in gastroenterology and internal medicine. He obtained his MD at Ross University and completed a Gastroenterology fellowship at the University of Connecticut.

He is dedicated to giving patients the most in digestive care. As a teenager, Dr. Do spent a lot of time with his father while he was ill in the hospital. Seeing the doctors caring for his father inspired him to pursue a career in medicine. “Working with gastroenterology patients in medical school and during my residency training showed me that I could make the biggest impact by specializing in digestive health.”

Dr. Do opened his own private practice in 2006. “Whether you need a routine test for a difficult problem, you will receive the kindness and attention you deserve at Advanced Gastroenterology. Our practice allows us to give you the level of care we would want for ourselves and our family members. The atmosphere in our office, the time we spend with you during your appointment, the state-of-the-art facilities at our Advanced Endoscopy Center…Every detail is designed for your safety, comfort, and excellent care.”

In his free time, Dr. Do enjoys to spend quality time with his wife and children. He takes pleasure in the outdoors, fishing, hiking, skiing, and playing tennis.

Samuel K. Sim, MD

Dr. Sim is board-certified in gastroenterology. He obtained his MD at the University of Alberta and completed a Gastroenterology fellowship at the University of Colorado. He joined Dr. Do’s practice in Vancouver, WA - finding a good match in Dr. Do’s patient centered practice.

Dr. Sim strongly believes in protecting your health and quality of life. “I always knew I wanted to be of service to others, so medicine was the perfect choice for me. I was drawn to gastroenterology because it is intellectually stimulating and allows me to play an important role in protecting my patients’ health. Whatever brings you to our office, I am here to make a positive difference in your health and quality of life…the reason I became a physician in the first place.”
