Every person is different — every situation is unique.
Dr. Dan Dinsmoor received his B.A. in Psychology from Oberlin College and his Ph.D. from American University in Washington, D.C. He completed postdoctoral training in family therapy at the Georgetown Family Center with the Georgetown University Department of Psychiatry. During the early 1970s, he developed an outpatient program for autistic children at the Regional Institute for Children and Adolescents in Baltimore. From 1983 to 1993, he served as Coordinator of Child and Adolescent Mental Health for Charles County, Maryland, and was also a staff psychologist with the Community Mental Health Program at Liberty Medical Center in Baltimore. For the past 30 years, Dr. Dinsmoor has been a psychotherapist in the Washington D.C. area, providing treatment to a variety of clinical populations including children, adolescents, and adults with attention deficit disorder, oppositional defiant disorder, depression, bipolar disorder, obsessive-compulsive disorder, and other psychiatric conditions.
Today, Dr. Dinsmoor’s practice focuses on psychotherapy, with interests in OCD, neurodivergence, and couples therapy. In his work with OCD, he uses Inferential Cognitive Behavioral Therapy (I-CBT), an evidence-based approach that offers an alternative to traditional Exposure and Response Prevention (ERP). He works with neurodivergent adolescents and adults, drawing on his extensive experience with neurodevelopmental and psychiatric concerns. His background in family therapy informs his work with couples, where he focuses on strengthening communication, understanding relationship patterns, and supporting meaningful change. For more than 20 years, Dr. Dinsmoor has incorporated neurofeedback into his clinical practice, often combining it with psychotherapy to support individuals who have not found sufficient relief through traditional approaches. Dr. Dinsmoor sees patients in Arlington and at Family Compass in Reston.
Dr. Dinsmoor is licensed by the State of Virginia and is a member of the International OCD Foundation, as well as the Association for Inference-Based Cognitive Behavioral Therapy.
