C. David Missar, Ph.D. at 3300 M Street NW Suite 201 is a psychologist’s practice in Georgetown’s upper M Street commercial district, providing the psychological evaluation, the psychotherapy, and the counseling services that the Georgetown professional and residential community uses for the professional psychological care that the licensed psychologist provides. The Suite 201 address at 3300 M Street NW, at the upper end of Georgetown’s M Street near the Wisconsin Avenue intersection, provides the psychology practice with the central Georgetown commercial position that the Georgetown professional client uses for the accessible mental health appointment.

The psychologist’s training, which involves the doctoral degree in psychology followed by the supervised clinical internship and the postdoctoral training that the state licensure requires, provides the Georgetown client with the most extensively trained mental health provider in the psychological treatment hierarchy. The licensed psychologist who provides the psychotherapy from the evidence-based treatment models, who conducts the neuropsychological and the psychological evaluation, and who applies the research knowledge of the psychological science to the specific clinical presentation develops the therapeutic competence that the Georgetown professional client values in the mental health provider.

The Georgetown professional patient’s therapeutic goals, which may include the specific symptom reduction for the anxiety, the depression, or the trauma-related condition, the personality and the relationship pattern change that the Georgetown professional’s repeated interpersonal difficulties require, or the career transition support that the Georgetown professional at the mid-career inflection point needs, are the therapeutic objectives that the professional psychologist’s treatment approach addresses through the specific theoretical framework and the clinical technique that the individual case requires.

The practice operates by appointment at 3300 M Street NW Suite 201.
