Minnesota Dr Recommendations

For those of you in Mn, what Dr’s do you recommend?
I have had my disorder for 13 years. My current neuro believes that it is CIPD due to all my symptoms (tingling, lack of reflexes, episodes of major weakness which then improve over time until next episode, etc), but won’t treat as the EMG was inconclussive for demyelination and my LP was normal. He now wants to do foot nerve biopsy although he said that due to the timing of onset there is a very good likelihood that it won’t show him what he needs to see to officially diagnose. Then, if that biopsy is negative he wants to biopsy a nerve in my arm…again with the understanding that it may also not show him what he needs to see to diagnose. At that point he may decide to treat via steroids, but this part was left hanging until we did more testing.
Also, does the Dr you recommend require a foot biopsy or are they likely to treat based on symptoms and history?
Thanks
