Questions about Bronson primary care

I've been going to the Bronson primary Care on West main for quite a few years. I've been seeing the same doctor and every time I see him I am more and more tempted to change doctors. However before I do that I need to know if it's a specific doctor issue or if this is a Bronson primary Care issue as a whole. I've had tests done for suspected problems and when those tests come back negative I get no follow-up. There's no attempt at finding another explanation for the issue at hand. There's not even a comment from him about the negative test result. I've also had issues with them responding to questions that I've sent via my chart. It seems to take forever, like days and days, for them to answer if they do it all.

So is this just a specific Doctor who sucks? Or is this par for the course for that practice as a whole?
