Brian Fung, MD

Medical School: University of California, Los Angeles, School of Medicine
Residency: Internal Medicine, UCLA Medical Center
Areas of Interest: One of the reasons why I chose to specialize in gastroenterology is because I believe that gastrointestinal health is a core component of one's overall health. Many gastrointestinal diseases, both mild and severe, can significantly impact our daily lives. I am grateful for the privilege of being in such an exciting and fast-growing field where I have the opportunity to meaningfully improve patients' quality of life.

Why the UArizona College of Medicine – Phoenix: I chose the College of Medicine – Phoenix not only because of the location, but also because the program has an incredible female leadership in place (with Dr. Alishahi being the PD, and Dr. Vela being the chief at the VA). On my interview day, I was genuinely surprised by how close-knit the fellows are with each other (i.e. going to taco Tuesday, hiking together). Moreover, I wanted a program that provides extensive exposures to procedures — and they delivered! We started scoping on day one of fellowship.

Why the UArizona College of Medicine – Phoenix: I chose the College of Medicine – Phoenix for several reasons. I felt the most like myself while interviewing with faculty during my interview. I liked the representation of women in leadership at the College of Medicine – Phoenix, specifically that our PD is a female. It was important to me to train somewhere that is a transplant center with exposure to all aspects of GI, which the College of Medicine – Phoenix is and has. I also chose the College of Medicine – Phoenix because of the obvious camaraderie between fellows during our pre-interview happy hour.
