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.

My experience was very pleasant. He listened to me very well and then suggested how we could solve my problems. I’m now waiting to receive an appointment for my swallowing procedure.

Brian Fung was great - the procedure went smoothly, the in-person staff was wonderful, everything was explained clearly and I felt well taken care of. I particularly appreciated that Brian spoke to me directly before and after the procedure. My only complaint is that it is incredibly difficult and burdensome to communicate with the center by phone (or any other way except maybe postal mail) outside the day of your procedure. Your only option is to call a person named Joanna who summarily doesn’t answer the phone, and then leave a message in response to a prompt which is meant to dissuade you from leaving a message - and then hope you are available when Joanna calls back. If you actually speak to Joanna, it feels like you won the lottery because you finally got through. You get the sense that the center is overburdened with “tiresome” questions and phone calls - but have they considered how this feels to a patient? Isn’t there a better way to handle this? I had questions about my prep that I wanted to ask but couldn’t.
