Query sort/display results by more than one field

Hi - i am not even sure how to ask this really.

I have some pages showing providers who work at a provider location. some providers work at several locations, and some providers work at one of several locations across any given health center.

For example - in health center A, Dr Smith could work at Main Street, or at Second Street. and his CPT info has both addresses.

what we want to show in the results page where I am loading the Post Grid shortcode is to sort the doctors by address

show the address one time, and under that, show the doctors at that location

then show a second address, if there is one, and show the doctors for that location there. And a third and fourth address if needed.

Does that sound possible?
