I was trying to reach this place for my husband who is a patient here but, for some reason he thought they were called the Core Institute of Neurology? I could not find a listing that matched the location and the type of specialist they are. When I called this number, it said, not in service! I found their were several locations, so I called the one on Thunderbird Rd and it was 4:41 PM, their listing said they were open from 8:00 AM to 5 PM and they were already closed! I feel that if you advertised you will be open till a set time, you should remain open till then! What a waste of time and very frustrating.
