“There is nothing, and I mean absolutely nothing, but phenomenal things to say about this facility.
“I received nothing but the most attentive medical care and compassionate nursing. I was checked on constantly, even when they had not one, not two, but three other very emergent patients arrive during the initial part of my stay. When there became a possibility that I might have to be transferred to a larger facility, they moved me to an inpatient bed for my comfort.
“No one ever wants to deal with emergency departments, but when you are in need of these services — it is so amazing to be cared for by those who truly love what they do, and I am so grateful that I had this team.”
