Took my 2 yr old son on New Year's Eve at 11 pm. They were very prompt and caring. Their treatment was right on the money. He had a very severe allergic reaction.

Everyone here was genuinely concerned, welcoming, and professional. They were knowledgeable and made sure I understood all possibilities, available services, and best practices. If I need them again, I know they will be my best option.

"Had we not taken our son to ER Katy, it's likely he wouldn't have made it through the night!"

"ER Katy Emergency Room saved our son's life. All I can say is that we went to an Urgent Care first, waited a ridiculous amount of time, and after we met [with our nurse we were] sent home. We did not feel comfortable with the "nurse" opinion; he seemed to be getting worse. At 1 AM, we rushed our son to a real doctor at ER Katy in the middle of the night and the doctor (real doctor!) and on-site X-Ray Tech found that my son's liver was cut in half. Had we not taken him to ER Katy (which was very local) it's likely he would not have made it through the night.

They reduced his pain immediately, the staff kept us sane and comfortable. The doctor made calls to transfer him to a specialist. ER Katy Doctors arranged everything. They were perfect, quick, professional, and efficient, and we owe them everything. They have doctors (real emergency room doctors) on staff 24 hours a day. I just thank God for ER Katy."
