Extremely knowledgeable and does mince words that need to said.
Amazing bedside manner. Extremely engaging and encouraging. Explained any questions we had and has reacted promptly to hopefully get through this quickly. Asked if we minded if my case was presented to other GI's, which means to me he is looking for the best answer for me, not just an answer that might help.

He is a good doctor with a brilliant mind. He actually read an article about a study for an alternative treatment I had found instead of dismissing it. He even gave me an idea of rotating two protocols.
He was very reassuring
Dr. Fang always helps and supports me in understanding other health issues in addition to GI issues
Just there for Fibroscan test
I appreciated that this Dr worked me into his busy schedule. I was hoping for help as I cannot swallow or eat. I was told "do the best you can" I already felt I was doing the best I could.

I would recommend him for his skill as a physician. However I could not recommend him on the ease of seeing him. His schedule is challenging.
Already did, brother in law has already completed his surgery with Dr. Fang.
It is difficult to hear that the pain you are feeling is 'all in your head', no matter how many times the doctor tries to sugar coat it. I know my pain is real.
They did not listen nor ask any questions that were related to my concerns. Very cavalier and dismissive.
I was impressed that I was given 15 minutes to over every question and scenario. I felt like I was the only patient this doctor wanted to visit with. It was very personal and effective.

Dr. Fang is outstanding!
Dr. Fang is all-around excellent in the care he provides.
dr. fang is a very caring and competent physician. he projects this in person or on video. i am grateful to have him as my long standing physician.
I appreciate Dr. Fang's expertise, which I need for my complex and ongoing medical challenges, but I cannot reccommends him because follow-up is nearly impossible with his over booked schedule.
Fine help.
