I have seen Dr. Dimar on 3 occasions and every time he was rude and didn't bother to take the time to listen to me or answer my questions.  He is cold, standoffish, and talks down to his patients.  If I could give him a negative score, I would!  I have had 2 other doctors read my MRI's now, and both found things he missed as he simply dismissed my pain. I will never step foot in his office again!
