- Branden Tarlow, MD, PhD

Dr. Tarlow practices full-spectrum gastroenterology and hepatology. He has a background as a basic science and clinical researcher. As a medical student Dr. Tarlow was fascinated with studying digestive diseases and became interested in liver biology. In clinical practice, he was drawn to the diversity of the patients and diagnostic challenges, but it was the ability to use endoscopy to diagnose and fix problems that he found most exciting. He enjoys guiding patients through a rough patch in their health, empowering them to understand their illness, and seeing them get better. 

Other Interests: 

Dr. Tarlow believes that the Portland area is one of the great places to live. He was born and raised in Portland and was excited to return after several years away. He loves the seasons, proximity to amazing outdoors, and culture. Outside of work, Dr. Tarlow enjoys trying to stay in shape, learning to garden, and keeping up with his active children.
