I do not recommend him and will never be back. After finding a cancer polyps and diagnosed for gastritis. He did not recommend any diet nor prescribed any medicine. When I asked him how to cure them he just told me whatever bothers my stomach or causes heartburn just don't do it. If I really need to hear that I wouldn't pay $1000 dollars for diagnosis right??? he is not paying attention and do not listen you... Worst MD i have ever been.

Strange I had an endoscopy scheduled and sat waiting for 40 minutes until my anxiety got the best of me and I walked out. Dr. Zierer never called to follow up with me or ask if I was even ok. I should've let that been my first warning. However, here I find myself on treatment and the more I read and review the more I feel failed by this doctor. Guess I was just another dollar sign. To those perspective patients, do your homework, ask questions, and hold him to a higher standard.

Highly intelligent, thorough and caring physician. Takes him time to understand your symptoms and comes up with a plan that is comfortable for the patient. I had an upper endoscopy with him and he and his staff were top notch. I would highly recommend him.
