Costas D. Hanjis, MD

Office staff rude & extremely unpleasant
Dr Hanjis told about staff & does not care
Dr Hanjis has failed to follow up on medical problems — has failed to return phone calls — or letters & has failed to deal with any problems — he abandons his patient when he fails to deal with concerns & or problems
Gives information to third parties against patient wishes even though info is not required by law to provide,
I would rate him less than one star based on my experience & the experience that my husband also experienced in all of the above

Dr. Hanjis has been my doctor for close to ten years. I’ve recommended him to so many friends, and they’ve all been thrilled as well. Dr. Hanjis is smart, kind, understanding and professional. And he has a good sense of humor to top it off. It’s like having a small town doctor in the middle of Manhattan.
The office is clean and nice. The medical secretaries and other staff are courteous and professional. You can’t do better than Dr. Hanjis.

Dr Hanjis has been my GP for approximately 3 years. I can’t say enough good things about him and his practice. I echo the other comments here about his patience, thoroughness and terrific empathy.
I moved to Dr Hanjis from another internist who I came to believe was too quick to prescribe tests and medicines for conditions with a low likelihood of being a real risk.
Dr Hanjis very carefully thinks through and explains to you what the pros and cons are of every path of inquiry and treatment. You will never feel «medicalized» but when it’s serious (I had a staph infection from an open wound last summer), Dr Hanjis will get you to the right people immediately.
If you can get to see him, you’re a lucky patient, there aren’t many doctors like Dr Hanjis

Great doctor! Very thorough, great bedside manner! Really listens and will spend whatever the time to get through everything with you. It’s so difficult to find a decent, let alone, a great primary care physician in Manhattan!
Office is a relatively easy location. Clean, comfortable and organized. Exam rooms are also very clean and organized. This is a MUST for a doctors office, nothing more disgusting then a messy, disorganized, and dirty office. Staff is professional and courteous.

I have seen Dr. Hanjis for close to 5 years now. He is the MOST amazing doctor I have ever been to. He makes you feel completely comfortable, even with things that are awkward to talk about. I’ve discussed my family history of cancer and he has been more than attentive to making sure I’m comfortable and aware of the game plan to make sure I stay healthy. I would recommend him to anyone, and if I ever leave NY I’ll probably come back just to see him for check ups!

Dr. Hanjis is hands down the best General Practice (Internist) I’ve ever seen. I have a history of cancer and was referred to him through an Executive Doctor Search Service. During my first visit, he took the time to get my entire family and medical history and was considerate, insightful and answered all of my (many!) questions with patience and with language I could understand.
Most recently, I called his office to make an appointment because I was experiencing chest pains and instead of the receptionist just transferring me to make an appointment, she connected me directly to Dr. Hanjis. He asked me what my symptoms were and we made an appointment for the very same day.
I would recommend Dr. Hanjis to my family, friends and anyone looking for the type of medical care that is precise, reassuring and comprehensive.
Thanks Dr. Hanjis!

Best doctor I have ever had. He took time and asked me questions about my life/​concerns that no other doctor has ever bothered with. He is professional, kind and thoughtful. He did all my tests himself which I’d never experienced and I was very impressed with his thoroughness. A co-​worker recommended him after I told her I’ve been going to urgent care since I’ve moved into the City (10 years ago) as no other doctor has come up to scratch from my former doctor in another state. He is the best!

Dr. Hanjis is a *fantastic* doctor. Can’t say enough good things about him. He is fairly young, but treats his patients like an old fashioned family doctor: He is kind, patient, gentle, sensible,… And he listens!

Amazing doctor. Exceptional bedside manner and very thorough. I absolutely recommend him.

Dr. Hanjis is an amazing doctor. He takes the time to explain tests, medications, procedures, etc… He is professional, makes you feel comfortable, and is extremely thorough. I’ve never had such a wonderful doctor and HIGHLY recommend him.

Yes!!! as good as it gets.
Professional, Courteous, and always return call when needed. Does not make you go through what you don’t need.
he is not in my network but I could care less. A good doctor whith whom you feel that comfortable is hard to find.
