I waited 90 minutes to see the doctor and finally had to leave to return to work. I attempted to…read moremake another virtual appointment at the front desk since the practice managed to draw my blood during the visit. I was told to call to make the virtual appointment, which I did. I called a few days later to ask for my blood test results and was told that they disposed of them since I left, even though I made a follow-up appointment. I was also told that the virtual appointment would be canceled because I couldn't speak to the doctor for the first time via a virtual visit. So, I wasted 90 minutes, plus travel time and endured a painful blood draw for nothing. I received no treatment and had to call 7 times to receive a copay refund. I also have to spend time ensuring my insurance company isn't billed. Additionally, I was told the practice manager would call me, but never received a call. Lastly, the front desk, nurse and biller were nasty on the phone. They argued and slammed the phone when disconnecting. I recommend avoiding this practice. They are disorganized, discourteous and do not care about treating patients.

I have seen countless Medical decisions made by the Oncologists at this practice that are complete malpractice. This office does not do up to date genetic testing or genomic testing for any of their patients. They would rather give ALL patients chemo for Monetary purposes than help their patients get new state of the art medications and help patients live longer. I am ashamed that I even worked at this practice as long as I did. IF you care about your loved ones, do NOT go see any of these Doctors. I promise you that they care about making money way more than they do about your cancer care. It is extremely sad and disgusting. It is 2023, and cancer is ever evolving, these Doctors are stuck in 1990's cancer care and it is very scary. I hope that the Medical board researches these Doctors and shuts this place down. I am not a disgruntled employee, I am a passionate person and I truly care about Cancer care. Patients come to this practice and trust that their Doctors are doing the best thing for them. I can assure you, they are NOT. Run as fast as you can from this office, and if you happen to come here, please go for a second opinion somewhere else. I promise you, the 2nd opinion will agree that this practice is morally corrupt! Do not trust these Dr's!! I don't care if they are Jewish and share the same faith as you, there are plenty other Oncologists in Brooklyn that do care about their patients. If I could could give this rating a -100, I would. Shame on everyone at this office for letting this go on as long as it has.

Besides my superb top quality medical team of Surgeons and Oncologists, I found the Nurses go above and beyond in their work, providing genuine care with such grace and pure empathy, often tending to patients as if family. Let's take a moment to praise the nurses. This year, 2025 I am a twenty years cancer survivor and visit MSKCC annually for my check up. It's key to stay informed and hopefully catch symptoms as early as possible. Sending prayers for healing and blessings to those who are going through the journey of one of the most difficult of diagnoses. Let us hope and pray they find a cure someday soon. Wishing you and yours a blessed healthy happy Thanksgiving. Thank you

ORIGIN: Memorial Sloan Kettering Cancer Center (MSKCC) was…read moreformed in 1980 when the first U.S. hospital dedicated to cancer treatment -- New York Cancer Hospital (1884), later renamed Memorial Hospital for the Treatment of Cancer (1899) -- merged with the Sloan Kettering Institute, a research institution founded in 1945 by philanthropists Alfred Sloan and Charles Kettering. CONCEPT: The hospital is dedicated to research and procedures (both inpatient and outpatient) associated with cancer treatment. LOCATION: This location represents the first and oldest site associated with MSKCC. It was constructed in the 1930s as part of what later became known as the Sloan Kettering Institute. SURGERY EXPERIENCE: This site (circa 1939) is not intuitive to navigate, the product of limited available space and development of new cancer treatments and associated technologies. Nonetheless receptionists on the ground floor provide the necessary guidance to get to your designated location (including specific elevators). Unlike the new MSKCC sites that are scattered across the city and surrounding suburbs, there appears to be little effort in making the main location peaceful or attractive. However it's important to keep in mind that MSKCC is highly regarded for cancer treatment, ranking second in the nation in U.S. News and World Report (2025) and first in oncology in Newsweek (2026). Hospital staff are professional, patient, and friendly making the experience less stressful. The staff appear to share a stance of not overwhelming patients with information, but are immediately able to answer questions and concerns as they are presented. That said, it's best to be familiar with the current and anticipated next step in care in order to make sure it is enacted as expected. Twice during the three day hospital stay there was need to point out an error in post-surgery protocol, and both were acknowledged and corrected (necessity of limited diet (liquid) and application of intermittent pneumatic compression sleeves to reduce likelihood of blood clots). Hospital meals can become the highlight of a patient's day. There are many options, including some offerings apparently inspired by menus at fine restaurants. Meat and fish dishes arrive well-done, perhaps due to being warmed under dome for long period between preparation and transport to room or prioritization of food safety. If the meals are not tolerable, alternatives in the neighborhood are abundant (e.g. NAYA, Chopt) as long as a way to get take out delivered to the hospital room (such as through a visitor) is navigated. Despite being located without a designated car drop off/pick up area along York Avenue, car pick up after patient discharge was well-orchestrated, and thus not as inconvenient nor difficult as we had anticipated.
