    Dr. Oas needs a four-year course in handling patients with respect. He also spent more time showing he know a lot of medical terms that he did allowing me to ask questions. At our first visit, my wife and I almost walked out of the room.

    Very forthright but done demonstrating great knowledge of his practice area. I find Dr. Oas is a blessing and appreciate his knowledge base in a presently unknown arena.

    He is rude, condescending and arrogant. I have cervical dystonia. He actually wrapped his arms around my head & torso to twist me into proper alignment. He did not tell me he was going to do that and actually HURT me a great deal. I screamed it hurt so much. My friend across the room heard my neck crack.
