Cornerstone used to be a good place for health care. I'm not sure if they have just started taking on more patients than they should or lost Doctors or something, but no matter how sick you are, good luck getting an appointment with your Doctor. They pretty much just send you to their urgent care for anything other than well visits which take several weeks to get in for so you pay twice as much for their urgent care service because you can't be seen by any of their primary care Dr.'s in a reasonable time period.
