Hi maureen,
For specific names, ask people you know/meet/trust, your other doctors and their staffs, your insurance company may have suggestions... and believe it or don't, even Angie's List.

For articles/advice, Google: "finding a good neurologist" (with and without quotes).

Try to find one who specializes in (limits their practice to) the specific condition you're seeing them for (e.g. PN, or even your specific type of PN). Once you've found a few candidates, call their offices to see if they're accepting new patients and/or under what circumstances (sometimes they say no, but will flex for certain cases, doctors' requests, etc.) Depending on your insurance, a referral may or may not be required. If so, ask your PCP for a referral to that neurologist.

HTH,

Doc
