Questions about your child's emotional and behavioral functioning 

According to the Child Mind Institute, 49.5% of American youth will have had a diagnosable mental illness at some point before they are 18. Early detection and intervention are crucial.

Questions about you child's development

A developmental delay occurs when your child does not meet developmental milestones (e.g., crawling, walking, talking, social interactions) at a typical rate. Developmental delays are common among children with underlying medical conditions such as autism spectrum disorder, Down's syndrome, and cerebral palsy. 

Please use the following developmental checklist to ensure your young child is on track to meet developmental milestones within the expected range.

How can a Licenced Educational Psychologist help?

A licensed educational psychologist (LEP) is a profession unique to the state of California. LEPs are school psychologists who have worked at least three years in a school as a school psychologist and are licensed for private practice through the CA Board of Behavioral Sciences.


LEPs possess a unique understanding of school systems and special education law, as well as expertise in child development, teaching pedagogy, and assessment. LEPs can provide support to parents and school-teams in ways that traditional psychologists and private practitioners cannot; LEPs possess first-hand experience regarding the rigorous path parents and school teams follow to support the learning of all students.

LEPs are highly trained to assess intellectual functioning, academic achievement, processing abilities, socio-emotional well-being, and behavior across home and school.


A licensed educational psychologist can provide a fresh perspective to parents and school teams through assessment and consultation.
