Debbie Jason, PhD


verified by Psychology Today

Dr. Jason is the co-founder and Clinical Director of Trauma Therapy CA. She also serves as a clinical psychologist for Orange County and a trainer for University of California – Los Angeles (UCLA)’s Center of Excellence.

Dr. Jason recognizes that relationships are challenging – even in the best circumstances. This is certainly true of parenting, which can be even more difficult when building a relationship with a young child who is oppositional or a teenager who may feel stressed, sad, or angry. Many parents blame themselves, feel isolated, and are unsure of what to do. Many teenagers feel alone, judged, overwhelmed or misunderstood. There is hope, though, in that you can be the solution! Through a unique approach, Dr. Jason works with people of all ages to help them develop their sense of selves, decrease stress, and establish rewarding relationships. Simultaneously, Dr. Jason coaches you to develop the necessary tools for promoting healthy relationships based on mutual love and respect. Having this space has helped many individuals understand and manage their lives better and allowed children to feel more secure and less interested in testing boundaries.

Your therapy experience with Dr. Jason will always be tailored individually to you and your strengths, with private sessions and distinct goals for each individual and/or family member as appropriate. The evidenced based practices drawn from, including Cognitive Behavioral Therapy (CBT), Trauma-Focused CBT (TF-CBT), Child Parent Psychotherapy (CPP) and Dialectical Behavior Therapy (DBT), have strong scientific support for treating depression and anxiety, strengthening healthy family bonds, improving emotional control and coping skills, and increasing positive relationships.

Dr. Jason received her Ph.D. in clinical psychology from Ferkauf Graduate School of Psychology and completed postdoctoral training at UCLA TIES for Families. She began her post-doctoral training at UCLA in 2015 before being promoted to Clinical Assistant Professor at UCLA where she provided clinical supervision to PhD students. (UCLA is consistently ranked as one of the top psychology schools in the country) She currently works as a Clinical Psychologist II for Orange County, serving children and adolescents in foster care, residential placements and juvenile hall. She also serves as a consultant for The DMH-UCLA Prevention Center of Excellence, providing bi-weekly trainings with a joint vision to help educate every single clinician and staff serving Los Angeles (LA) County’s Department of Child and Family Services (DCFS) on Trauma and Resilience Informed Care. Dr. Jason is also Foundationally Trained in Dialectical Behavior Therapy (DBT) by Behavioral Tech.

Dr. Jason’s specialty is working with children and families who have been exposed to trauma or are currently experiencing stress of any kind. At Trauma Therapy CA, you can meet with Dr. Jason for individual therapy to address a wide range of concerns. Dr. Jason also provides superior cognitive, developmental, psychological and personality testing to help differentiate between conditions that have similar symptoms but very different treatments, such as trauma responses vs. ADHD vs. learning disabilities vs. anxiety.

Liane Mitchum, PsyD

Dr. Liane Mitchum is our resident authority when it comes to therapy for anxiety and depression in children and teenagers. She is a clinical psychologist with an awesome personality coupled with a passion for treating youth who have been exposed to trauma. Dr. Mitchum is highly competent to treat those with a history of physical and sexual abuse, anxiety disorders, adjustment disorders, cognitive challenges, ADHD as well as depressive and other mood disorders.

Dr. Mitchum is determined to understand and help you understand how trauma and stress can impact physical, mental, and emotional health. Her knowledge, coupled with her deep compassion, results in therapy centered around your individual needs within a healing environment that fosters safety and trust. And for many of her clients, trust is the first step toward healing.

Dr. Mitchum started her career as a therapist treating adults who were court-mandated for therapeutic services, many of whom were referred by the Los Angeles Department of Children and Family Services (DCFS). She has also spent time working within a high school setting and conducting psychological testing for children and teenagers within a Department of Mental Health (DMH) contracted facility. She has worked across levels of therapeutic need serving children, adolescents, and adults in community-based clinics, school settings and most recently, residential facilities for children and youth in foster care. Trauma Therapy CA is lucky to have her as a resident trauma expert when she is not treating patients at her other governmental positions.

Dr. Mitchum received her doctorate in Clinical Forensic Psychology from the Chicago School of Professional Psychology in Los Angeles, CA. She completed her internship with Orange County Health Care Agency, where she was quickly invited to continue on as staff. Dr. Mitchum is also an expert at helping you understand your diagnoses through comprehensive psychological evaluations resulting in psychological reports to provide to clients, clinicians, and other professionals to help you to more deeply understand your struggles and your strengths.
