    Well, I had my first appt at Dr. Dickson-Witmer office which went well. 3 months later I went for a follow up and was sent for an MRI. I had another appt. scheduled for 2 PM, was told to be there 15 min. early so I was there at 1:45, at 3:05 I was still in the waiting room and was not able to wait any longer because of other responsabilities. I went to the receptionist told her I had to leave an to have Michelle call me with the results of my MRI. I never got a call so I have called the office two times, the first time I was put on hold for 12 minutes, the second time I was put on hold for 8 minutes. Because I was at work I had to keep hanging up. To date I still have no results of the MRI.
    Just not right.. so now I need to find some other place to go, needless to say I am really disappointed with my experience.
