This was the best experience I have ever had at a hospital bar none. The staff, the physicians, the ease of getting around and the efficiency of everyone was way beyond what I had expected. When I saw the large amount of people waiting in lines and in waiting rooms I thought I would be there forever. However, the lines moved quickly, patients in the waiting rooms were seen fast and the time the providers gave me was as much or more than I had ever experienced. Needless to say, I was extremely impressed. Thank you very much.
