Most of the reviews that you see here on Yelp for this office are old and some are not directly toward their service for surgery. You can check they're reviews on Google and they actually have 4.8 stars. They probably now have new management or something.
I just had my two molars pulled and from the beginning till the end they took great care of me. One of the assistants even brought me outside on the wheelchair to the car that I was gonna ride on the way home.
I love this place. I recommend it.
