Dr. Hanna has retired, but the dentist who replaced him at his clinic located on the Lake in Lake Oswego was not at all patient with children! I brought my son to him because he was a pediatric dentist and felt he would be more sensitive to the needs of a child. My son had to have three fillings and was just 3 1/2 years old. The dentist shamed him for being scared, scolded him for being afraid of his tools and threatened him with pain if he "mis-behaved". I have never been so appalled in my life! We immediately found a new dentist, Dr. Pike, and have been THRILLED with his staff. They were able to fill all my son's fillings in one sitting without a whimper from him. They told him he was the boss and he didn't need to be afraid. They were so patient and skilled with children it made the whole event NON-eventful! Just the way it should be for a little child. I normally don't write negative reviews and of course this is just my personal experience, but I would really check this clinic out before I would take a young child there.
