    This will probably be the most detailed review that I have ever in my life because I have a few complaints but its time to let this go. I've sat for months of disappointment with the treatment that has been recieved by case management at this hospital. So much that has expressed to family, friends, and coworkers its time to everyone that takes the time to read this review. I say case management specifically because my issues were not with doctors and nurses. Before I begin, 1st let's start with their mission statement, "Mount Sinai South Nassau’s mission is to provide high-quality, comprehensive, and easily accessible health care to residents of Long Island’s South Shore." I was met with complete disrespect by the director of case management when I brought my aunt who has dementia hadn't slept for a month, swollen ankles, begging for food compulsively and having massive temper tantrums. Me as a caretaker with a full time job in total distress begging for help, never said I was abandoning but was continuously told I was by the director. Next, I was told that they were sending her home by ambulette and if I didn't answer they were calling the cops. That was a baseless unnecessary threat to someone that has taken care of my mom who passed from ALS, my dad who died at the hospital in February, and my Aunt for the past 5 years with my Mom watching over her before she got sick. I've taken care of my elders, never asked for help but doors close when you do for elders who may make a little too much, dont have savings, or proper healthcare that's just a fact I'm learning as I navigate this process. And I did call cops as well but it wouldnt have went over. I was floored on that comment and didn't say a single word which led her to hanging up the phone followed. Oh I was also told she's not sick she has dementia...cant decipher that statement my Aunt has been in my life for 50 years if she isn't sick I dont know what is. My Aunt only has Medicare but they failed to provide my Aunt and me with the care that is expected at a hospital. I spent days looking for a solution, stayed up until 5am and finally came across a program that is funded through Medicare, sharing it with anyone who is experiencing the same issues, the organization is called ianacare. Maybe they should have informed me of this organization instead telling me they were going to call the cops that was so hurtful 😢 all I needed was help but easily accessible healthcare was not an option for.Mount Sinai case management director. I could also go back to when my father was in the hospital dying as well because case management was pushing to send him home when he hooked to oxygen and couldnt walk anymore. And I am telling them that my son and I was taking care of him for months but I can't handle him with his inability to walk. I did it with my Mom and she was 100 pounds and it was difficult. Or the fact that I am still waiting for my father's death certificate with COPD which he suffered for from years. He died in February its July now - this workflow process should have never be a difficult one because I gave the hosptial all of this information as soon as he was admitted so that his hospital bills were covered. They have his primary doctor for over 30 years, and the COPD doctors and social worker information as well. Delaying this prevents his family from getting the benefits that he is entitled to and makes me feel like its no priority because he is dead. It would have probably been zero stars if it weren't for the doctors and nurses- you guys are amazing ❤️

    I recently had a great experience giving birth to my first baby here. Everyone made me feel welcomed and cared for. My nurses and doctors were attentive to me and my concerns. I truly think about that day often. So thank you, Shenade, Sherry, Dr. Winkeler, Dr. Rangan, and Dr. Dean, for making my first experience an unforgettable one and one that feels impossible to top.

    I came here for a rather invasive biopsy, 6:45AM appointment. The staff was prompt, personable and professional. Every person encountered during the ensuing four hours was caring, informative, helpful and very concerned for my well-being and comfort. I could not asks a question because there was no reason to: all questions were answered before I had the chance to ask. They really covered everything, every possible scenario and outcome. And even told me whom to call, just in case, over the July 4th holiday weekend. A wonderful experience.

    This place is horrible and highly unsafe. Nurses take forever to come. My father was on a neuro floor. They don’t arm the beds consistently. No sense of urgency when alarms go off…lack of attention to detail. His monitor was detached after a scan for the entire afternoon without anyone noticing but my sister and I. The mri machine was broken for a week - how do you run a hospital like that.

    Absolutely horrible ED. Came in at 1pm, it’s 4 pm and I still do not know who my nurse is. Came in for excruciating migraine, no IV as yet , no pain medicine, no antinausea meds, no fluids , nothing as of yet (I am also a nurse, so I do know proper protocol). I’ve had a patient screaming next to me for the past 2 hours and no one is coming, it got to the point where I had to go to the nursing station (which nobody was at and everyone kept walking away).I had to do a head CT and they had me sitting on a stool waiting and patient family member on a wheel chair. The staff are not friendly here and they clearly do not care about the patients. They don’t check on you and they don’t know how to prioritize care. Go anywhere else.
