Which NC hospitals did you experience? I’ve found that Duke in Durham and Wake Forest Baptist in Winston-Salem are excellent and was surprised to not see them listed.
I forget the name now its the teaching hospital huge place and family was there for cancer treatments.
Huge place.
Having worked for one of Harvard's major teaching hospitals for a couple of decades I have a pretty fair knowledge of where to get the best medical care.
I'll mention cities rather than specific hospitals: Boston,NYC (Manhattan),Baltimore,Philly,DC,Durham NC (Duke),Atlanta,Cleveland,St Louis,Rochester,MN (Mayo Clinic),Dallas,San Francisco,LA.
The more serious the particular condition you have is,or the more uncommon it is,the more you want to be getting care in one of the major hospitals in one of these cities.
