I found a BUNCH of doctors through the iLearn mentor site...

I emailed probably around 14 doctors and got back maybe 6 replies.
One of the hospitals near my school also have job shadowing programs where you fill out a form and they can set you up with the kind of doctor of your choice, so check out the websites of the hospitals and see if you can find something like that.
I don't know if you go to school near a DO school like I do, but if you do definitely take advantage of that. I've met a few doctors who are awesome that work at the school and will give me phone numbers and emails of other physicians who are in practice. If you volunteer at a hospital or are in a position where you can talk to doctors ask around and see if they know anyone. That's how I've found all my docs.
Good luck!
I've learned a lot through shadowing.
