child, adolescent and young adult psychologist in Newport Beach and Irvine Calfiornia

Dr. Aaron Montgomery, Psy.D., ABSNP
Licensed Clinical Psychologist

Dr. Montgomery is a clinical psychologist in Newport Beach whose work centers on long-term, psychotherapy with children, adolescents and adults. He believes meaningful change comes from being deeply understood, from making sense of one's history, relationships and inner life within a steady, thoughtful therapeutic relationship.

He has worked with children, adolescents and parents across a range of clinical settings. He is also a specialist in psychological, neuropsychological and psychoeducational assessment, and a Diplomate of the American Board of School Neuropsychology. When questions about attention, learning or development are part of the picture, careful evaluation brings clarity, and that understanding becomes part of the work.

His clinical foundation also includes training in evidence-based treatments, including Cognitive-Behavioral Therapy (CBT), Parent-Child Interaction Therapy (PCIT) and Trauma-Focused Cognitive Behavioral Therapy (TF-CBT). This gives him a broad, practical perspective that he integrates thoughtfully into depth-oriented care. His doctoral research examined the therapeutic alliance, the quality of the relationship between therapist and client, and its role in meaningful change.

Dr. Montgomery supervises doctoral-level clinicians in training. He has presented original research and has served as a Subject Matter Expert for the California Board of Behavioral Sciences, developing the LMFT Clinical Examination, and for the California Board of Psychology, developing the California Psychology Law and Ethics Examination (CPLEE).
