Licensed Clinical Psychologist PSY #36392

Meet Dr. Josue Sibrian, a Licensed Clinical Psychologist, Licensed Educational Psychologist, and Board Certified Behavior Analyst (BCBA) with decades of experience in neuropsychology and Applied Behavior Analysis (ABA). He specializes in comprehensive psychological and neuropsychological evaluations for children, adolescents, and adults, helping individuals and families gain clarity, answers, and practical guidance.


Dr. Sibrian provides thorough, evidence-based assessments for a wide range of neurodevelopmental, learning, behavioral, and emotional concerns. His areas of expertise include autism spectrum disorder (ASD), ADHD, learning disabilities, executive functioning difficulties, traumatic brain injury, anxiety, depression, obsessive-compulsive disorder (OCD), and other developmental and neurocognitive conditions.


He completed his psychology residency through the Los Angeles County Office of Education and the Los Angeles County Department of Mental Health, followed by specialized postdoctoral training in neuropsychological and forensic assessment at Northview Los Angeles Psychology Group. This diverse clinical background allows him to provide evaluations that are both scientifically rigorous and highly relevant across educational, medical, and legal settings.


Known for his compassionate and collaborative approach, Dr. Sibrian uses state-of-the-art, evidence-based assessment methods to deliver accurate diagnoses and personalized recommendations. He works closely with clients, families, educators, and healthcare providers to translate evaluation findings into clear, actionable strategies that foster growth, resilience, and long-term success.
