To give just 5 stars is not enough, they deserve 100 of them. Let me tell you that I've been seeing…read moredoctors for years and got used to chronic pain as noone could fix it, but Dr. Greuner diagnosed the problem within 5min of my appointment. I had an AVM surgery. He showed me every scan of my arteries and explained everything clearly. I felt calm before my surgery only thanks to him. This is the best care and treatment you can get, not just in New York, but worldwide. I came from Europe to specially see dr. Greuner and glad I did. No wonder he is ranked as top 5 doctors in the world. He is so carrying, knowledgeable and genuinely an amazing person. The staff and dr. Tonis were so friendly and welcoming, they took the time to explain everything in detail and answered all the questions that I had. They followed up after the procedure to make sure everything was good with me before my traveling back to Europe. They don't just treat you, they make sure you leave their office healthy, pain free and with a smile on your face. I can't thank you enough how you changed my life. From constantly being in pain to being pain free, really increased quality of my life.

I was extremely fortunate to be treated by Dr. David Greuner for AVMs at NYC Surgical Associates…read more As someone who previously had many bad experiences with other doctors including being misdiagnosed multiple times, I'm so happy there's someone like Dr. Greuner (and the rest of the staff) who genuinely cares about his patients and listens to them not only during procedures but also prior and post. I would give this practice a 100 stars if I could.

I rarely, if ever, write reviews. However, I feel compelled to write one for Dr. Miller. He is…read moretruly an outstanding physician who has saved my life at least twice. I have been under his care for over two years now, since I was referred to him by Columbia University's medical center. Dr Miller is attentive and thorough. He ensured that I was properly diagnosed and that I followed through on my drug regimen to ensure minimal side effects. He came to see me everyday when I was in a hospital and followed up regulary after I was discharged to see to it that I was recovering. In fact, once I forgot to carry my medication on a trip, and he called in an emergency prescription at a pharmacy near me on a SUNDAY! A SUNDAY! His network is great too. He referred to a surgeon who was phenomenal in helping me with another issue. The only qualm I have is with some of the office staff. It can sometimes be challenging to get them to get a prescription to the right pharmacy when you need it most. I am fortunate to be on his service and I would not hesitate for a second to recommend him

I've been trying for 6 weeks to get my provider to send a px for the medicine they prescribed. Many…read moremany calls later, to both practice and pharmacy, I have nothing to show for it. It's impossible to talk to the doctor without paying the copay for a visit, and I'm not confident that even that would yield positive results in the form of a medicine being delivered. I've not had this problem with other providers who have staff dedicated to dealing with pharmacies. I feel unheard.

October 1, 2026. Visit to the emergency room of Lenox Hill Hospital of Northwell Health at 9:30…read moreAM! Great care from the minute I walked in the ER entrance to the great PA, who took care of me, my nurse, and all the staff. I was treated like royalty, and even had a great patient relations employee by the name of Melissa Torres stay by my side to make sure I was comfortable and treated with kindness! Immediately tests were run on me, blood, chest X-ray, EKG after triage. I came in with shortness of breath and palpitations. Wow, wow wow!! The best ER treatment of any hospital in the New York City area! Highly recommend!

I was admitted in February 2026 for severe abdominal pain related to my gallbladder. While some…read moremembers of the staff were kind, my overall experience left me feeling unheard, dismissed, and frustrated. The biggest issue throughout my hospitalization was pain management. On multiple occasions I waited hours for prescribed pain medication despite repeatedly telling staff I was in severe pain. I often felt like I had to plead or even cry before my pain was taken seriously. A resident Dr. Nomen would also delays in receiving IV medications that had already been ordered. Communication was inconsistent. One nursing assistant recorded a temperature of 100.9°F and said she would notify the nurse, but when the nurse arrived she told me I did not have a fever because she had never been informed. I also repeatedly asked several physicians about the results of my IgE allergy testing and was told someone would follow up, but no one ever did. I eventually learned the results would take about a week. There were other frustrating moments during my stay. Despite discussing food allergies, I was served chicken for lunch and told there was no other option. Maintenance requests, such as replacing the toilet paper, were never addressed while I was admitted. My interactions with some physicians and residents also lacked empathy. I felt my concerns about pain control and treatment options were dismissed rather than discussed. Instead of collaborative conversations, I often felt rushed or spoken to in a condescending manner. Discharge planning was also disappointing. I was told follow-up arrangements would be made with my primary care physician, but no new appointment was scheduled. Staff pointed to an appointment I had already made months earlier and presented it as though they had arranged it. I recognize that hospitals are busy and that not every member of the team provided poor care. However, patients in severe pain deserve timely treatment, respectful communication, accurate follow-up, and compassion. I hope this feedback encourages improvements in patient communication, pain management, and discharge planning. Also, I didn't feel it was appropriate that Dr. Andrew Price reached out to my internist due to them going to the same school or squatting in front of me like he was Megan the stallion. Lastly, the resident Dr. Nomen called me rude and was very condescending when stating "I could leave hospital" during my discharge. She obviously didn't care for me, if I was probably a "married" woman she wouldn't have used that tone with me. Overall, her acerbic attitude was appalling.
