On a recent visit San Francisco, one of my front teeth broke causing some immediate pain and a need for a dentist. Asking some relatives, some were patients at Dr. Cohen's office. When I called the office, they said their schedule was completely booked that day but that Dr. Cohen could see me if I could come at closing time, which I did. Dr. Cohen still took his time explaining to me in detail what work would be required and said he would fit me in that week to complete the work. I found Dr. Cohen to be very friendly and knowledgable in his field. I felt comfortable with him doing this work. Although my vacation took a dental turn, all turned out well with my mouth. He fixed my tooth and I only wish he was my regular dentist. I would highly recommend Dr. Cohen.
