i wish all the doctors I have to see are like Dr. Gerdis. He sees the patient not the illness.

by Marc Bobroff on Dec 22nd, 2014

Very approachable physician, caring attitude, makes you feel comfortable in his presence. Interacts with you on a level devoid of a behavioral presentation of intellectual superiority as is common with many individuals who hold doctorates. A gentleman and consumate professional in every sense of the word. Recommend to anyone who needs a accurate diagnosis and a competent examination.

Loved the Dr. Gerdis, Have not seen him since 2003 becasue i moved. Try to obtain my medical records and the medical records person Teresa Wong has no idea where my records are becasue in 2007 they changed the system they use to use. so i guess my records were trashed. She gave me Mt. Sinai's & Beth Israe's medical records number even though i have never been admitted to either one of those hospitals and of course they do not have my records because they do not have records of you unless you have been admitted there. I then called Teresa Wong and she had nothing new to say, i called the Hartsdale office again and they see my name in the system but no records and no idea where they say the least i am very disturbed!

Dr. Gerdis has been my doctor for 14 years. He is, without doubt, one of the most compassionate, intuitive and caring doctors I've ever met. He has seen me through all sorts of illnesses -- some serious -- and his steadfast, intelligent manner has never wavered. No matter what, he calls you back almost immediately. Sometimes within the hour which is unheard of. He is a great diagnostician. Years ago I had a very troubling eye condition and he sent me to another doctor who sent me to someone else. No one could figure out what was wrong. I was terrified and he called me every night to see how I was doing until the condition was corrected. We could afford to go to a pricier NYC or Greenwich doctor in private practice but I value his expertise and humanity to go to anyone else.

He is such a great Doctor. Now and days Doctors do not care like they use to but this Doctor is REALLLY good. he calls you back within minutes and he does not give up in finding your health issue. He really works with you and really is a passionate Doctor. I recommend him to everyone.

Dr Gerdis is a very nice dr, but I would have to say the last few visits was awful for me. The first time I have visited this dr I thought WOW what a great dr, finally I can findout whats going on with me....well lately all he does is ignore how I am feeling and when I explain my symptoms all he does is tell me I need medication like xanax for my anxiety, or depression meds because he thinks I am depressed. He has prescribed me medication for all the wrong symptoms I am definitely not depressed, I do have anxiety after going back and forth to this dr explaining my symptoms and he is doing nothing for them. I have not felt like myself in over a year and he constantly makes me think I am crazy. I will not be using this dr any longer, I need a dr who will take my symptoms serious and help treat them instead of calling me crazy.

Dr. Gerdis has an excellent, caring, soft bedside manner who cares a lot about his patients. I will be forever gratefull to him for his quick diagnosis and immediate referral for very painfull preianal ancess condition which i had taken care of on two different occasions--quickly and succesfully.He does not force procerdures upon you but usually gives on tine to feel 'comfortable' with it first-- up to a certain extent.

Dr Gerdis is the quintessential professional. He has been my doctor for more than 8 years. Besides that his diagnoses are always accurate, he genuinely cares and goes the extra mile to ensure that his patients have the best options. I highly recommend this doctor.
