I'm from the pharma industry.

From my experience. Is best to check the Google reviews first and see which clinic got the most star

Usually there will be a Dr there that is very good with patients. So try to see that particular Dr.

Doesn't matter if it's chain or not. Chain doesn't mean good. It's the Dr that makes it great

So anyway, most clinics survive through panel patients. Those on chronic medications, will come and take their usual supply which is sponsor by their own company

Yea that's why, find those with like 100 reviews or more

If just 10-20 reviews, then really have to think it through

Or if you have close friends in pharma line. Can ask them which dr is good.
