About Jachi Sun, M.D.

I care for all GI conditions but also have extra fellowship training in all interventional procedures and enjoy a challenge. Additionally, cancer care and prevention are near and dear to me. GERD and Barrett's esophagus are my current focus, and the incidence is on the rise.

Why Gastroenterology?

I immediately liked GI while in medical school because it provides a mixture of preventative care and care for life-threatening conditions. It also combines young and old patients, males and females and allows for sharing the joys and trials of walking with patients with acute and chronic conditions.

What Can Patients Expect?

Patient-centered focus where we provide respect, compassion, and good listening coupled with comanaging and offering the best medical care.
