David P. Celani is a licensed psychologist who practiced for more than twenty-five years in Burlington, Vermont. In treatment, he focused on his patients' "attachment to bad objects," which manifested through their inability to separate from parents, friends, or marital partners who demeaned, criticized, or abused them. Celani now presents workshops throughout the United States on Object Relations theory. His books with Columbia University Press include Fairbairn's Object Relations Theory in the Clinical Setting and The Illusion of Love: Why the Battered Woman Returns to Her Abuser.
