S. Gerald Hann, DEd
As director of the practice, Dr. Gerald Hann is a registered psychologist with three decades of experience helping children, adolescents, adults, and couples enrich their lives and find freedom from self-defeating behaviours, anxiety, and depression. He holds an assistant professorship in Dalhousie University’s Department of Psychiatry. He frequently presents and regularly provides supervision to a wide variety of mental health professionals, including psychologists, psychiatrists, physicians, and counsellors. He routinely offers treatment to healthcare providers and, in particular, offers assistance with identifying and remediating unconscious and maladaptive emotional patterns that could trigger countertransference, thereby negatively affecting them and/or their patients/clients.
Dr. Hann has 15 years of post-doctoral training and experience utilizing Intensive Short-Term Dynamic Psychotherapy (ISTDP). He is one of only two consultant psychologists who offered patient treatment for the Diagnostic Interview for Stress Disorders pilot project, which served as the foundation for the Medically Unexplained Symptoms Clinic at the QEII Health Sciences Centre, a service that has operated continuously since 2009. Dr. Hann offers clients at his practice the same treatment they would receive at the Medically Unexplained Symptoms Clinic but with quicker access than through the public system. Common presenting problems for which clients seek treatment include functional neurological syndrome, psychogenic pain, vomiting, seizures, dissociation, nausea, irritable bowel syndrome, emotional numbing, and many other common manifestations of somatic symptoms.
​
In addition to providing consultation and treatment using ISTDP, Dr. Hann also has interest and expertise in working with neurodivergent individuals across the lifespan. His early experiences as a teacher, coupled with being a National Certified School Psychologist (NSCP; USA) has created a strong foundation and understanding of school-aged children and adolescents, suspected to be neurodivergent and/or on the autism spectrum. Dr. Hann is also keenly interested in working with adults suspected of being on the spectrum (with possible trauma issues), who may experience difficulties coping with emotional states and impairment in social interactions in later life.
