Although Dr. Diers seems to know what he is doing, the treatments on my child were not without stress. Some of this was a result of his approach to the patient...actually his attitude and his technique. My child said he was a little rough and that he was impatient and did not listen to him. He certainly has a busy office, and his staff, though efficient, seems too much like a well-oiled machine. The focus is too much on Dr. Diers' efficient practice and not enough on the individual person/patient. From a parent's perspective, I did not realize that Dr. Diers was deciding to make a strategic switch in the child's treatment approach until several weeks after the fact. I had no idea that some of what he has lately recommended was a possibility until now, when we are two years into the treatment. Initial good impressions have turned very cautious.
