Marion Domain seems like a very large and very impersonal conglomerate. However I see a dentist there who is delightful and very careful. He made the experience almost painless. His nurse was lovely too.
Sometimes the staff on the front desk come across as rude and dismissive. I know they are often busy but they could go home and practise smiling in front of the mirror sometimes.
Some medical staff seem to be under the impression that just because they do work in a professional environment they are superior to the ordinary individual.
