    I was told he had a very good bedside manner and was very disappointed. We had a basic conversation and it was obvious he had not even seen the ultrasound results. Two different times he asked what I thought about what he said and I clearly stated that I was there to figure out next steps regarding a biopsy. The explanation he gave about waiting three months and not answering questions was ridiculous. What was even more upsetting was in the clinical notes in the middle of his long paragraph, he stated that I said I requested some kind of monitoring instead of what I thought was the next steps of a biopsy. Beyond disappointed and would never refer anyone to him. One of his statements after I said this would be good if anything comes up and they catch it early and I didn’t want to wait three months. He clearly said in three months it could get really bad or maybe not. He then walked out without saying if someone will be coming in shortly or if he was just going out to get something. I waited five minutes in the examination room before I walked out to find somebody and figure out next steps. I would definitely not recommend him to anyone I care about.
