Great Doctor been going to Dr.John Koval for years . No complaints

Submitted May 16, 2023

Not happy with doctor's diagnosis without complete exam and proper testing, I went to another doctor and discovered that I have a serious condition that will require constant follow-up with more endoscopies. I really liked him and was disappointed with the outcome when I developed serious pain and swelling of the abdomen.
