It is all very confusing. It appears Northside Medical Midtown includes Northside Hospital Cardiovascular Institute-Midtown Atlanta and other medical specialties.
Northside proper is a real hospital with an emergency dept. Same for Northside Cherokee and Northside Forsyth, both of which are well north of Northside proper. Northside Midtown is a huge MOB., that might look like a hospital to many.
Confused yet? It is sort of like Atlanta and Peachtree Streets.
