This hospital is the worse . I came in by ambulance with a massive nose bleed that lasted more than 40 mins , my blood pressure was 154/90 because I was nervous I don’t suffer from high blood pressure and they said the blood pressure caused the nose bleed. They stopped the bleeding and sent me home no ENT to examine me. I just found out I have a stage 3 tumor in my nasal cavity that grew into my brain that was the reason for my nose bleeds, and loss of smell. They didn’t care , came asked 2 questions 30 minutes later was sent home.

DO NOT go here for a severe emergency, and for woman DO NOT go here to have your baby. In 2019 I went here because I had an on going fever for 5 days. They sent me home saying it was. UTI (although I never had any symptoms of a UTI) and 3 days later I went to Winthrop Mineola and they found that I had an ongoing perforation in my colon and the follow day my body started going into shock. They almost killed me.
In 2022 I went here to give birth to my daughter (only because my doctor was affiliated here) and they left me out in the hallway for 3 hours SCREAMING at the top of my lungs in labor. It wasn’t until they finally gave me a room and checked that I had gone from 3cm-7cm in 1 hour. I started throwing up all over the floor and hall way and they never even offered my a wheelchair until the very end. My experience here was absolutely terrible.
When my daughter was born they didn’t even bring her to me for over 10 mins for our first touch. I hate this place and I’ll never ever step foot here or recommend anyone to go here.
They even misspelled my daughter’s first name and I’ve had years of headaches trying to change it on all her records. Save yourself and do go here or have your baby here.

Currently waiting in the ER and the wait time has been ridiculous. I’m going on 3 hours just waiting. Waiting area is practically empty. One lady just walked out. They need to do better. So quick to take our insurance information though…

The worst hospital ever. With all the money put into renovations in the ED I was never examined till I was leaving, never checked by a nurse.and never, given a drink or asked if I needed anything. I Laid on a cot for hours. The nurses just sat in front of a monitor all day. Being a nurse myself I never saw anything like it. Finally left at 4pm since 10am. Never again!!!

If you have an autoimmune disease and need help, come here. I’ve been in and out of the hospital for years but specifically lately since sep 26th 2025 in another hospital. Me and my dad got fed up and decided to come here during the weekend of thanksgiving. What a greatness decision that was because this hospital ACTUALLY HELPED ME and found the problem causing me extreme pain and inflammation aside from my autoimmune disease. Contributing and making it worse for me when the other hospital and even my own specialist couldn’t tell me what’s wrong for what felt like forever. Which is measurable by a simple blood test btw. I needed help with my flare, was dehydrated. The details are messy and gross. The hospital staff and doctors were really helpful. They did multiple blood tests on me a day and monitored everything. Watching over me and my condition diligently. They are busy and in the middle of transitioning with Mt Sinai taking over South Nausea Hospital and they still managed to take good care of me. I’m used to going to other hospitals and having good nurse care but with doctors, that’s a little more difficult and communication and cross examination/consultation can be hard. But here at Mt Sinai, not only did I have a whole team of doctors, but I saw often. Even the detoxes I requested I got to see. That too time cause they were in surgery which I understand but I wasn’t get go until I saw all I requested. The doctors didn’t want to let me go either until they go to the bottom of my issue. I have an autoimmune disease yes, but they not only teamed up to communicate and work on me to find the problem, but they kept me in hospital until they did. After all the testing they found out something more that has to do with another organ in my body. It sucks having more health issues BUT what a GREAT feeling to not only be cared for, genuinely and carefully with my condition, but for the doctors to believe me and find the cause of the issue which gave me a sense of relief and validation. As someone who’s been in and out of the hospital and in treatment for years with an autoimmune disease that had no cure, that is SO IMPORTANT and I really appreciate my team of doctors at Mt Sinai. I even took some referrals from St Sinai to go to theirs doctors who also do outpatient because that’s how much they’ve gained my trust in their abilities to actually HELP and treat my disease and I feel like my future will be better in their hands. Please go here if you have an autoimmune disease and need help. The process of help and treatment sucks but at least here, you’ll get the proper medications. I need to be on IV when I am sick and other hospitals always try to get me to do PO medication ASAP while I’m vomiting but the doctors here understood that I needed everything through IV until I could get stabilized. They understood how delicate my system is and right away knew which medications I can and cannot take. There are some medications that can cause a high mortality rate and they have a lot of knowledge on my disease and I appreciate it. If you’re wondering what my disease is just in case you have some issues that are the same or similar I have pancolitis. It is a severe form of ulcerative colitis. But it is IBD a.k.a. irritable, vowel disease nonetheless. Which they do understand here and they have a good team of gastroenterologist and I love the primary care that I received as well. They’re very knowledgeable about this autoimmune disease and it feels good to finally have a place that I can go to for safety and trust that I’ll be in good hands if something happens to me again in the future. I appreciate the care here and I highly recommend this hospital.
