“My father was a patient in the Mount Sinai South Nassau Emergency Department and the Critical Care Unit. He received excellent care delivered by extraordinary medical and nursing professionals. This was an extremely difficult time for our family, and the staff went above and beyond to help us. The nurses on the Critical Care Unit are all wonderful. No task or request was too difficult and was handled with expertise and dignity. We are very grateful to everyone for their professionalism, support and kindness during this time.”

“My elderly mother was brought into the Emergency Department of Mount Sinai South Nassau. I want to share that I and many of my other family members have been patients, caretakers and visitors in many other hospitals, and never have we experienced patient care such as that displayed by your staff. From doorman to surgeon and everyone in between, we were treated with the utmost professionalism, respect, compassion, dignity, smiles and eagerness to accommodate and please as much as possible.”

“My daughter was recently seen in the Emergency Department. I wanted to let you know how kind the whole staff of South Nassau Communities Hospital was! Also, the next day when I needed to obtain her records, the staff was wonderfully helpful. I live closer to another hospital, but Mount Sinai South Nassau will always be my first choice!”
