Joe,
Colorado's a big state, lots of small towns and a couple of larger towns/cities. You didn't state or maybe I missed it what like of place you're looking for, small town, remote mountain town, urban, suburb, etc...

Right now it seems Boulder county is one of the friendlier places, but parts of it are a little on the expensive side.

Are you on a fixed income? Are you 100% disabled or will you still need to find work?

As far as finding a doctor to get your recommendation - once you get here, ask here or around the place you move too. It's not going to help you any, to give you the name of a doc in Denver if you end up moving to Grand Junction...
