--while Mayo does have a world-class neurology department, a lot of anecdotal evidence from people who've gone there doesn't seem to speak well for their expertise in the particular area of peripheral neuropathy (they seem to have more knowledge of other neurological syndromes).

When it comes to peripheral/neuromuscular disorders, I think Johns Hopkins, Cornell-Weill/Columbia, Jack Miller, Washington University St. Louis, University of California/San Francisco, and Jacksonville Shands may be better bets (all of these house some of the world's leading researchers into neuropathy).
