In phoenix on a business trip I woke up at 1am with stabbing abdominal pain. I came in to the ER and was seen immediately. RN Beverly G was friendly, knowledgeable, and sociable and really helped me feel at ease... which isn't the easiest thing at 4am while exhausted, in awful pain, and pantsless.
Everyone I felt with was professional with a good sense of humor, and made the several hour stay go by quickly. They never left me alone longer than 30 minutes at the longest and kept me updated on my situation and test results constantly.
I only wish they were near home, because it was a far better experience than any I've found in Denver!
