When I originally scheduled my appointment, I clearly stated that I wanted to schedule at Sherman Hospital.  The schedular went over the appointment with me and said that it was at Sherman Hospital.    When I appeared at Sherman Hospital the girl that checked me in said I was supposed to be at Good Shepard Hospital.  My wife was sitting at the table when I scheduled, so we/I know it wasn't the confusion of a 79-year-old man on my end.    Central scheduling needs some work on your part.  We need to be able to schedule at the hospital, not some scheduling center that is not vested in the process.
