About me

Dr. Janzen completed his doctorate in clinical psychology at George Fox University in 2005.

Currently, Dr. Janzen conducts comprehensive interdisciplinary diagnostic evaluations through the CDRC Child Development clinics. Areas of specialty include attention-deficit/hyperactivity disorder and learning disabilites.

Additionally, he is involved in individual therapy cases and supervises intern therapists offering treatment to children, adolescents, and families, specifically in areas of cognitive restructuring, behavior management, and emotional regulation. He also provides intervention services, in conjunction with a team of highly specialized medical providers, within both the Pediatric Feeding and Swallowing Disorders Clinic and the Healthy Lifestyles Clinic.

He has worked in a variety of community, university, and hospital based environments providing services to children, adolescents, families, and adults.

Your insurance company will also be able to inform you of any copayments, co–insurance, or deductibles that will be your responsibility. If you proceed in scheduling an appointment and your health insurance benefits do not participate with OHSU providers, your out of pocket liability may be higher.
