My guess is that I have multiple GI issues that we are trying to address at the same time. It sounds like it is a complicated process but the Doctor is doing a good job of explaining it to me. If I have questions the Doctor is fairly prompt in responding and is pretty good at explaining the answers.

National Jewish Health PatientDecember, 2021
Again, no one quite like Dr King hos bedside manner and breathe of knowledge are superior.

I had not seen Dr. King in over 3 years but he spent time going through my previous visits to address my GI problems. He also made suggestions about seeing a [a specialist for symptoms] I am experiencing in other parts of my body. He listens intently and explains everything in plain English so I can understand easily.
