5/5
Dr. Moiseiwitsch provides a superb professional service and is, beyond that, pleasant to deal with. He is careful and thorough, offers good explanations of alternatives and possibilities. I've never had the least qualm about working with him in what is definitely not a fun procedure. My history with this doctor includes two root canals. I can compare those with other dentists I've seen for others
