I was only here for an X-Ray which meant I didn't need any appointment or anything. Came in, did very light paperwork, and waited about 10 minutes (it was moderately busy) before being taken to the machine for the scans and being given the disc and written report. The staff was nice, understanding of my situation, and even helped figure out my insurance stuff when I had forgotten my card.
Simple and quick, which has been my experience at multiple locations from this group.
