Therapists
All therapists at the Psychotherapeutic Ambulance of the University of Siegen are licensed psychological psychotherapists with the expertise in a recognized guideline procedure (behavioral therapy, depth psychologically based psychotherapy or analytical psychotherapy) with years of experience.
