Could you clarify what institution you mean by "Rockefeller"?

I did a Wikipedia search and it looks like there are several options in New York.

This isn't as big a deal at Rockefeller as it might seem, as they already have attached apartment buildings that most of the graduate students and much of the faculty live in.

Do you mean all essential employees?

I assume, Rockefeller University. It's a large hospital on the upper East side.
