Miriael Holliday-Unzaga2025-07-24 Great staff and doctors quick results it a great place to go for emergency or health reasons. S B2025-07-24 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!? Ayana Pratt2025-07-24 Amazing staff, doctors, and care.
