Lyndhurst, NJ |
I find Dr. Zierer and his staff excellent, easy to make an appointment and everything else after that, its the second time I came for an examination and went for another examination in the Clifton office the same friendly staff from the appointment to the end all excellent including a follow up call from the office the next day to find out if all was ok with me. Big thank you.

Tells you the truth about your condition and possible solutions.If you have any questions he will answer them promptly and coherently.
New York, NY |
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.
