My initial visit to mayo in Rochester was 4 days. A lot depends on what tests they’ll accept from your previous facility. It was my experience that they wanted results from their own testing. Another factor is the logistics of having that many appointments and scheduling them without any overlap. I worked with scheduling and my pre-coordinator and they were very helpful. It might be a little overwhelming at first but if you get comfortable with your schedule and get to know the footprint of the campus you will be okay. I had a liver transplant because of cancer and just celebrated my third anniversary on 4/10.
