Every one from the front desk, to the ma’s, nurses, doctors and techs were quite caring, understanding and were attentive to make sure I was comfortable and cozy.

   Trustindex verifies that the original source of the review is Google. I went in with chest pains and shortness of breath. I have insurance but it’s not in network. I live close by so I went to the nearest emergency room. I was greeted and made aware that I might have to pay self pay if the Dr deemed it not an emergency. After getting an ekg the Dr said it wasn’t an emergency and they proposed I pay over $1800 to be examined. The Dr said what do you have Medicaid, making an unfair assumption. I replied no I have Aetna insurance. I politely declined and had to go somewhere else. They were nice overall but why the outrageous charges!?
