From the time I stepped into the emergency room, I had nothing but the best care. The nurses were respectful and had great bedside manor, they were very thorough with my whole treatment. I was then sent to a floor where I had the best nurses. They answered my questions day in and out. Doctors would come and talk to me and made it so I could understand what was going on. I was there for 5 days and every nurse I had was great and I thank everyone of them for taking such great care of me!
