What People Say About Dr. Chester Zahn, MD
RecentHighestLowestMost Helpful

Dr. Chester Zahn is a doctor who truly cares for his patients’ health! Before my grandmother passed away peacefully, she had been going to Dr. Zahn for many years and treats him as her primary doctor. There was one incident when my grandmother was home alone and called Dr. Zahn’s office. On the phone, Dr. Zahn reported that he couldn’t hear my grandmother make out any words. Dr. Zahn immediately realized that something was very wrong. He called the ER and ordered a CT Scan and treatment to be prepared and ready. He personally went to my grandmother’s home with the ambulance and its team and found her on the ground unable to speak and unable to move her body. She was suffering from a stroke! He took the ambulance with her to the ER and followed her for her whole hospital course. Thanks to Dr. Zahn, my grandmother received the treatment she needed and was successfully discharged and was able to walk again after some rehab. She went on living another healthy 15 years thanks to Dr. Zahn!

Doctor's manner was very rude and no patients to listen to his sick patient and patient's family when they asked him questions. The medicine he prescribed causes a lot of side effects.

Dr. Zahn an his staff were very rude and unprofessional. I would not recommend anyone to this Dr. or office. When asked very basic information, he was abrupt, rude, demeaning, judgmental. He so uncaringly told me that I would, for the rest of my life have to stop.... He seemed angry, during my 2 conversations with him.
