I've worked in healthcare settings, and I've seen nurse practitioners screw up too many times. I highly recommend having an MD as your primary care provider. A board certified internal medicine specialist is the best bet for an adult.

Ordinary nurses can get to be real smart about a specialty area that they've worked in for a long time. But nurse practitioners working as PCPs are supposed to know a lot about a lot of things. They just don't have enough preparation for that to be true.

NPs tend to be people who liked school and enjoyed taking a lot of courses. They got where they got because they were good at studying for tests. But they often don't have all that great of a background in actually working as nurses.
