I know that this isn't a traditional way of finding a doctor...but about a month ago someone named "Diabevita" started following me on Twitter. I clicked through and found that the twitter user was representing a family medicine center in Scottsdale, Arizona that specializes in Diabetes management.
Interesting, I thought. I ended up clicking around their website and making an appointment.

I'll let you know how it goes.
