Licensed Psychologist 


My name is Priscilla Hsieh and I am a Licensed Clinical Psychologist (PSY29746) who specializes in working with children and adolescents. I attained my Doctorate in Clinical Psychology (Psy.D) from the California School of Professional Psychology, Los Angeles in 2016 and completed my clinical training in various settings that include outpatient mental health clinics, hospitals, and school settings.

My clinical training and experiences have been focused solely on working alongside children/adolescents and their families and providing assessment and therapeutic services that addresses a wide range of psychological and behavioral issues. I have experience working with children

struggling with depression, anxiety, parent-child/peer conflict, academic issues, and behavioral challenges, as well as children with developmental delays.

At Gunn Psychological Services, I primarily conduct psychological evaluations for ADHD, Intellectual Disability, Autism Spectrum Disorder, Academic Testing/Learning Disorders, and mood-related disorders to children and adolescents (ages 2-18). I have a genuine passion for not only helping children understand their unique cognitive profiles, but their parents as well by connecting them with the appropriate resources and bridging understanding to help strengthen family relationships. I warmly welcome the opportunity to meet with you to see how I can be of service to you and your family.
