It looks like they still have not worked out their mobile express system. Does not work. With an appointment, I still waited 45 minutes. BEWARE, so you are not treated like Cattle, be certain to sign in on their paper check in clip board, and mark that you have an APPOINTMENT. Otherwise you will just sit there waiting and waiting, just like most offices for the Medical profession in the Las Vegas, Nevada area. Wish I had know before I moved here. Ugh!
