  • "Best Attitude and Bedside Manner"
    Advance ER on Inwood was absolutely the best ever and I've been to quite a few in my 71 years. They have THE best attitude you could ever imagine and their bedside manner was awesome. Annette, Dr. Allen and Paul were outstanding in their field.

  • "Good Customer Service"
    Very good customer service. Not only addressed medical issues, but also socialized and made me feel more important than a number or statistic.
    - J. Scott
  • "Best ER Experience"
    This was, hands down, the best ER experience that I have ever had or could ever imagine. This may be better than any doctor's office visit too. The facility was gorgeous, everyone was extremely nice
