Famous quotes containing the word professional:
“The belief that there are final and immutable answers, and that the professional expert has them, is one that mothers and professionals tend to reinforce in each other. They both have a need to believe it. They both seem to agree, too, that if the professional’s prescription doesn’t work it is probably because of the mother’s inadequacy.”
—Elaine Heffner (20th century)
