I have been using Cornell facilities for more than 20 years, and their level of maintenance and professionalism is outstanding.Dr. Costas Hanjis has been my primary care doctor for almost 20 years, and we have developed a great relationship during this time. He is very thorough and very caring with his patients, but the best of all is how he listens to them. He is the best!

I’ve been going to Dr. Hanjis’s for many years and he’s very attentive; he listens unhurriedly, which is rare. His demeanor is pleasant and friendly. I always feel well taken care of

Dr. Hanjis is a wonderful and caring primary care physician. He was my doctor during the period of around 2009-2015, and saw me through a number of health crises. Then, I lost touch with him and, regrettably, saw another PCP in New Jersey. This doctor had an intensely rude staff, was very hard to get appointments with, and in general gave bad advice. I was so very thrilled to re-connect with Dr. Hanjis via Weill-Cornell in 2020, and my health and life has been better for it. So, I know the difference between good and bad PCPs, and Dr. Hanjis is a great doctor!!

Always a pleasure. A great clinician with a winning manner.

Dr. Hanjis is an experienced doctor. I found him knowledgeable, attentive to the patient and offers good advice.

This was my first time at Dr. Hanjiss office. I was taken right away. The office was very clean and all staff were very personable. Dr. Hanjistook additional history on me and was very interested in keeping me healthy.He suggested some tests for me for certain conditions and explainedwhy he felt I should take them. They took bloods and he responded to methe day the labs came back. I felt good about having found him for a primary care physician.

Dr. Hanjis is, and always has been, as thorough, amiable and excellent a physician as one could wish for. I now live 2 1/2 hours from Manhattan and have no intention of changing my internist.

Excellent, caring and professional experience. He listens and explains his understanding of my medical issues and rationale for treatment recommendations. And is open and responsive to all questions. Cannot recommend highly enough.
