Dr. Patricia E. Zurita Ona, or Dr. Z., is a clinical psychologist who specializes in OCD, trauma, all types of anxiety and related conditions, and emotion dysregulation problems for children, teens, and adults. She has doctoral-level specialized training in treatments based on Cognitive Behavioural Therapy (CBT), rooted in behavioral interventions.

Dr. Z has participated in formal intensive trainings in various forms of CBT and is the director and founder of the East Bay Behavior Therapy Center, a private therapy center in Walnut Creek, California. Her work has been significantly shaped by Acceptance and Commitment Therapy because she finds that it brings radical behaviorism alive with compassion, awareness, and scientific backing. In addition to private practice, Dr. Z. is a clinical faculty member for the Wright Institute, and regularly attends both national and international conferences.
