We aren't 'on duty' here at smd.  Some posts lay around a little
while before anyone replies.

When I was in dental school, the clinic had summer staffing and
patients weren't left dangling with unfinished work.

Can't say what's going on with your situation with that university.

I'd call the main clinic number to see if there are any messages
about summer hours and maybe even a way to talk to a live person.

Best wishes,
