During the exam, almost at the end, my son tried to touch the optometry machine. The doctor slapped with force his arm away from the machine and told him it costs hundreds of dollars to clean and he was not to touch it. It almost made my son, who is 11, cry. I was shocked. I didn't know what to do. After the exam was over, I asked his assistant if the rest of Jensen's appointment could be with a different doctor or just with her because we'd had a bad experience. She asked me what happened and I told her and she essentially told me I was lying and was visibly angry. She went to talk to the doctor who approached me aggressively and said he did not hit my son. I told him I witnessed him slapping my son's arm to which he responded, "do you want to pay to have the equipment cleaned?" I said that there are other non-physical ways to correct someone and that my son did not know that he was doing something bad. He said "Well, I'm sorry, and if you want to leave there will be no charge."
