About Brian Fung, M.D.

Why Gastroenterology?

I chose to specialize in gastroenterology because I believe that gastrointestinal health is a core component of our overall wellbeing. Gastrointestinal diseases can have significant impact on our daily quality of life. I am grateful for the privilege of working in a fast-growing field with advancing research and innovation where I have the opportunity to meaningfully improve how my patients feel.

What Can Patients Expect?

I am dedicated to providing high-quality, evidence-based, individualized care. I believe in listening to my patients and working together as a team to come up with a personalized care plan. Patients can expect to receive the highest standards of care from a physician who is up to date with the current guidelines and latest developments in the field.

Dr. Fung is a consummate and knowledgeable professional. He took the time to explain processes and procedures and it is clear that he cares about people.

I have been suffering for many years with stomach issues. Was passed on to the next Dr or if simply just ignored. He not only heard, but he listened to me.validated my feeling about my symptoms. We are still solving the mystery, but he hasn't given up.

This is by far the best experience I’ve had with a colonoscopy. Doctor Fung is a very personable and kind person. He communicates well and he does everything he can to accommodate his patients needs. When I had my pre op appointment, he was on time. When I had my procedure, he was early which I love. The staff at the office is equally good. I highly recommend Doctor Fung.
