Arizona Neuromuscular Research Center

Phoenix shows 29 listings under Medical Research Institute, but that count hides how much contact detail sits behind each name. Of those 29, 27 list a phone number and 28 list a website, so nearly every entry gives you a way in, though at least one listing has no website at all. None of these 29 carry a Sponsored tag, since paid placement for this category hasn't launched in Phoenix, so the order you're scrolling through is plain directory sequencing, not a promoted lineup. Zip codes 85004, 85022, 85028, 85034, and 85044 each hold two listings, and the rest spread thinner across the city.

If you run one of these institutes and your phone field is blank or your website link no longer works, you can claim the listing and fix it yourself. That matters most for the entry without a website, since anyone researching it has no digital way to check first. Call two or three numbers before settling on a contact, since nothing here is ranked by quality or fit.
