I had to complete a wellness screening at Sonora Quest for my job. I was unable to setup an appointment through my job site so I knew going in that I would have to wait. I signed in around 8:55 am on 10/28 and the place was PACKED! There is a sign right beside the sign-in sheet that stated walk-ins should be prepared to wait at least one hour. I waited exactly an hour before nurse Barbara called me back. Although it took an hour to be seen, Barbara was very nice and super-fast. I was out by 10:10 am. Here's the sad part... people that had appointments for 9:00 am and 9:30 am were still waiting when I left. It may be best to walk-in and wait an hour if you have the extra time. You will be waiting for an appointment, too.
