      I was very pleased with their hospitality and the way they treated me as a patient. The facility is very nice and made feel right at home. The receptionist, nurse, and the ER doctor were awesome. I have no doubt in my mind that if I need to go to an ER room, that it will be this facility.. good place….good people!
