Dr. Mayer Hayer Zayan, MD

The doctor is very knowledgeable and attentive to my mother’s needs

Horrible! He should NEVER treat anyone with mental illness!! He was condescending judgmental and just plain mean! He told me I was enjoying my depression because I had everyone feeling sorry for me and then for my anxiety and depression he told me that I needed to read Psalms!! He was not open to helping me out with my medication, I do have to say that he did get me on one medication that was needed but not the right dose that doesn’t excuse the way he treated me! My Medicare was billed $200 for a 60 minute visit and he wasn’t here for more than 20 minutes the first time. He was still arrogant and dismissive regarding my declining mental health! He cut my prescriptions in half so that I would have to make another appointment with him as the time came for my prescriptions to wear out he decided to reschedule my appointment and then gave me a problem about refilling my prescriptions!! My pharmacy tried to contact him three different times regarding a prescription that the insurance… wouldn’t cover due to the way he wrote the prescription he never got back to them until three days after I ran out of my medication!!! I thank God that I wasn’t suicidal that first day he came to meet me because I probably wouldn’t be here today to warn other people! DO YOUR RESEARCH! I wish I had!

This doctor and his wife should be arrested. They are defrauding innocent elderly ppl.

Dr Zayan has been seeing my mother for several months. It is challenging for her to get out. Doctor and his assistant come to her home. Take time with her and never rush. We love him! He coordinates care if anything special is needed. Always answers his cellphone and encourages us to call.

Unkind and dishonest. The Bernie Madoff of cardiology.... shameless .

I was always tired and had no energy. Dr Zayan was the only doctor to find the cause, a heart murmur. Having Scarlet Fever as a child with high fevers caused the valve damage. The other doctors before him just wrote my symptoms off and gave me vitamins and B12 with iron shots. He found the cause. I will always, be grateful for what he did for me.

I can truly say that I miss Dr.Zayan. He was able to tell me my diagnosis before even performing a biopsy. When all the other doctors were calling it cancer. Some times he was rude but he never sugar coated anything;always kept it 100 and that's what I loved. Good old fashioned honesty. It kept me healthy. Please hurry back!

Dr. Zayan has provided excellent care to my mother for several years now. He has always answered his cell when we needed him and has been very caring. His staff in Buffalo Grove is professional also. I have never had any complaints.
