Dr. Gregory John Zanieski, MD

Dr. Zanieski is fantastic surgeon. He is one of the best, incredibly knowledgeable, smart, well seasoned surgeon who performed double mastectomy due to breast cancer. The minute I met him I knew that I can trust him with my body and with the fact that he will make the best decisions in my diagnosis and on the operating room. He did, my case was not the easiest and he made best medical decision on the operating room which ultimately resulted in fantastic outcome. I am cancer free. I could have not wished for anyone better because he just is the best. He is very humble, kind and down to earth person. Thank you Dr. Z!

I had 2 surgeries. Dr. Zanieski is the very best! He explained everything step by step. He is very kind and compassionate. I am very thankful that he has played a very large part of my breast cancer treatment.

With out him I would not be here, he is the BEST

I have never had surgery before and Dr. Zanieski completely put me at ease. His ability to convey information and thoroughness along with a patient and mild mannered temperament was soothing and much appreciated. I felt that I was in the good hands of a competent and talented surgeon.

Did a great job with my lumpectomy!. Caring and informative.

If my diagnosis of bilateral breast cancer was a black cloud, Dr. Zanieski was the silver lining. While his surgical skills were exemplary, there was far more to Dr. Zanieski. He listened attentively to every redundant question I posed, and answered thoughtfully and patiently. His focus was always on the positive outcomes, allaying my fears and emotional stress. He was an advocate when I needed one. Dr. Zanieski is a humble man who is clearly devoted to his patients and work. Every member of his office staff, including reception, scheduling, billing, and especially Mary Beth, his nursing assistant, were sensitive and compassionate and went out of their way to make a difficult situation acceptable. I will always be grateful.

I unfortunately was diagnosed with breast cancer and was referred to Dr. Zanieski. I can't say enough wonderful things about him. He is so knowledgeable, caring, patient, never rushes you out of his office. The surgery went well (unfortunately a mastectomy was needed), but thanks to Dr. Zanieski, he gave me the confidence to heal. Having to go through many biopsies and tests before the surgery, this man actually called me at home with the results. Few doctors will take the time to do this. He is high on my list for one of the best breast surgeons at the Dyson Center.

I cannot praise Dr. Zanieski enough (staff too!). I had a large Phyllodes tumor removed by him recently. I saw him at the Dyson Center in Poughkeepsie. He was caring, knowledgeable and takes his time to answer any and all questions. He is a true professional and I feel extremely fortunate to have been referred to him. HIGHLY recommend!
