  • Nov 16, 2018

    They were AWESOME! Doctors did a good job calming my nerves, nurses were quick to call me back when I had questions about the procedure beforehand, and the whole process was smooth. I was also under sedation during the procedure, and they made sure that I would arrange to be picked up by someone I know (best not to allow people to take rides from Uber when on drugs!) I also requested a room change because I realized I wouldn't be able to afford the room with IV sedation, and they were kind enough to shuffle things around and help me out. Smooth service!
