WebMD / Yelp review for Ambulatory Anesthesia Associates

"I had a bad outcome with this same anesthesiologist... She was supposed to provide anesthesia during dental surgery. Prior to surgery she assured me she would monitor my state until I woke... But when I woke up I was in pain so bad that I could barely speak but she had left."
