This question already has an answer here:
I'm struggling with grammar and the name of a group of clinics; let's say that there are five dental clinics colocated in the same building, and the name of that group is Foo Dental Clinics. There's a single entrance, a single greeting desk, but five distinct dental clinics beyond the main entrance.
Foo Dental Clinics is located at 56 Foo Street, or Foo Dental Clinics are located at 56 Foo Street?
This is for an audience where the convention is American English: collective nouns generally take a singular verb (Microsoft is a company). It's the fact that the collective noun seems plural that's messing me up.
This question establishes that American convention for collective nouns (Google, Congress) are treated as singular, but the fact that this collective noun appears to be plural, and the plural of the things it encompasses, makes this a bit harder to figure out.
