Dr Ottosen has done several root canals for me as well as other dental work. I am very satisfied with his work! I've had dental work done by at least a half dozen different dentists and Dr Ottosen is by far the best. His staff is very courteous, professional, knowledgable and friendly. At one point I was referred to him to correct a mistake another dentist had made. I have a real phobia when it comes to dentists, I've had nervous breakdowns before and have unreasonably high standards when it comes to medical/dental staff. I can honestly say I am impressed with every aspect of treatment I've ever recieved from Dr Ottosen and his staff!!
