    Excellent, knowledgeable, thorough, informative physician. Could be short, interrupted frequently, but he knew his area and that is why I came to OSU!

  • Reviewed on Apr 30, 2021

    Took lots of time to go through my issues and explain what was going on both my health and what he was planning for my future care.

    very knowledgeable

  • Reviewed on Apr 14, 2021

    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.

  • Reviewed on Mar 21, 2021

    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.

  • Reviewed on Mar 16, 2021

    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.

    very good.he was super informative and clear about the possibilities of my outcome or cause for my illness

  • Reviewed on Apr 08, 2020

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

  • Reviewed on Mar 29, 2020

    detailed and seemed concerned about me

  • Reviewed on Mar 08, 2020

    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.
