    very knowledgeable

    It was hard for me to explain what has been going on with me. I felt he only got one aspect of my symptoms. Has not answered my concern about the meds, given to me.

    he is not the best communicator, and unorthodoxed in bedside manners, but I have complete faith in his ability. He is highly recommended by other docs for my particular problem.

    He was condescending and rude. He was way too rough with the physical examinations as he became angry at me for not following his vague instructions perfectly. He patronized me for the entire hour. He would tell me to walk a certain way and then "turn around" and get angry if I didn't turn the direction that he wanted. I wanted to walk out of my appointment 5 minutes into the visit, but I waited 2 months for this appointment and was using/wasting my PTO.

    While sometimes insulting, he was very professional thorough, explained things well. I felt very confident in his diagnosis.

    detailed and seemed concerned about me

    Dr. Oas appeared to be very knowledgeable but talked too much about irrelevant matters, such as the minds of engineers and astronauts. In the end, he was rather dismissive of my medical condition and referred me to another specialist. I didn't get a straight answer to my condition until I read after-visit summary and saw a mention of ataxia. That prompted me to research the condition and decide what form of ataxia I probably have.

    Dr. Oas is an exceptionally knowledgable physician who diagnosed me after a decade of other doctors missing it. For that, I am tremendously grateful. His condescending manner of speaking was upsetting however. He did not care about my concerns nor did he let me talk. He expressed the uniqueness of my case to the medical student but continued to treat me as though I was stupid. I was a paramedic previously & would have given him a piece of my mind, had I not been desperate for his help. I suspect that he is well aware of having the upper hand, therefore doesn't mind belittling his patients. If another physician had his level of expertise, I would never see him again. But, I will continue because I have no choice if I want adequate care. To receive that care, the trade off is leaving feeling as though your an ignorant half-wit. He could also explain your diagnosis to you directly rather than the student. I grabbed bits and pieces through their conversations. I had to google the diagnosis to grasp a better understanding.

    I felt he was a very bad communicator. He corrected my answers, was very hard for me to talk to him. he cut me off mid sentence, was intimidating, I don't feel I can tellhim my concerns or clarify instructions.
