Hello @wsmith7, Mayo Clinic is one of the most respected names in healthcare worldwide. In the US there are three campus locations. Jacksonville, FL Phoenix, AZ Rochester, MN.

There aren’t any clinics located in Arkansas. However, you might look into Unity Health. They’re a member of the Mayo Clinic Care Network which is a select group of independent health systems that are granted special access to Mayo Clinic's extensive knowledge and world-leading medical expertise.

I’m not familiar with Arkansas but I see on the Unity Health website that they have 44 locations, so hopefully there may be a facility near you. Are you experiencing a particular health issue?
