--while neurologists are not known for their bedside manners or senses of humor, the best place to go (if you can) for diagnosis and treatment of neuropathy, and neuromuscular conditions in general, are tertiary level medical centers that are also teaching centers. Some of these have specialized subcenters for neuropathy or neuromuscular conditions.

Massachusetts General, Cornell Weill in NYC, Jacksonville Shands, the Jack Miller Center in Chicago, Johns Hopkins in Baltimore, and the University of San Francisco come to mind.

The advantages of these places, beyond the resources, is that many of the practices involve doctors who are also researchers and who are very much informed as to the current state of diagnosis, testing, and treatment. Moreover, at such places often the doctors involved are salaried employees and can therefore spend more time with patients; they're not always looking for volume.
