Suffering from kidney stones and they took care of my painPosted on Cynthia GonzalezTrustindex verifies that the original source of the review is Google. 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. I honestly hate hospitals, or ER’s; Post Oak ER has changed my mind. I would gladly go back and will not hesitate to take any members of my family and friends. Thank you so much Post Oak ER.

Great staff and doctors quick results it a great place to go for emergency or health reasons.Posted on Ayana PrattTrustindex 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!?Posted on Soumaya AlissaTrustindex verifies that the original source of the review is Google. Amazing staff, doctors, and care.
