Authority Site Case Study: How an Air Force Flight Surgeon Took His Side Hustle Full-Time

I first met Ryan Gray at New Media Expo in 2014. He introduced himself and when I asked what he did, he said he was a doctor.

Turns out that Dr. Gray, along with his wife (also a doctor), was building MedicalSchoolHQ.net, a resource for med school and premed students.

It's another perfect example of building an authority site around a particular area of expertise.
