The Developmental Lens:
A New Paradigm for Psychodynamic Diagnosis and Treatment

The Developmental Lens: A New Paradigm for Psychodynamic Diagnosis and Treatment is the result of nearly thirty years of private practice, deep research, clinical supervision of candidate therapists in training, and teaching in psychoanalytic training institutes.  At its heart is a three-fold purpose: one, to
demonstrate the dynamic course of developmental processes from birth into
adulthood through my original Model of the Seven Keystones of Healthy
Development; two, to demonstrate the Seven Keystones of Wounded
Development—what compromises healthy development as the result of
environmental and relational failures and acute and cumulative unresolved
trauma; and three, how to work clinically in these seven pivotal keystones for
healing and for transformed development. Innovative theory-making and
clinical applications seen through vivid case illustrations serve as my
contribution to contemporary psychodynamic/psychoanalytic theory and practice.
