If convenience outweighs your health, then stick with the doc you have. It wasn't meant to be a glib response, but if your doc is incompetent or unwilling to deal with you in a manner that you see fit, you need to shop around. Maybe it's different north of the border, but ultimately the patient/client always has a choice, even if the choice is to NOT patronize a certain doc.

But hey...it's only your helath we're talking about.
