Dr. Bryan Hill spent his career working as a pediatrician, teaching at a university, and working at a hospital. But in March 2016, he decided he no longer wanted a boss.

He took some time off, then one day he got a call asking if he’d be up for doing a house call for a woman whose son was sick. He agreed, and by the end of that visit, he realized he wanted to treat patients without dealing with any of the insurance requirements.

Then he learned about a totally different way to run a doctor’s office. It’s called direct primary care, and it works like this: Instead of accepting insurance for routine visits and drugs, these practices charge a monthly membership fee that covers most of what the average patient needs, including visits and drugs at much lower prices.
