Areas of Clinical Interest

Dr. Reiersen is the child & adolescent psychiatry assessment supervisor for the First Contact Assessment Service, which evaluates individuals who are showing early signs of a possible psychotic disorder such as schizophrenia. In addition to assessment by a psychiatrist, First Contact assessments include diagnostic interviews and cognitive testing by a psychologist. The First Contact Assessment Service generally does not follow patients over time, but provides evaluation reports to the treating psychiatrist. Before making an appointment with the First Contact Assessment Service, patients should already have a treating physician who is willing to provide ongoing treatment. In order to facilitate communication of treatment recommendations, the contact information for this treating physician (usually a psychiatrist) should be provided prior to scheduling the evaluation.
