About Sarah
I'm a New Zealand Registered Psychologist providing comprehensive ADHD and autism assessments, alongside behaviour assessments for children and young people.
In addition to private practice, I work in Special Education supporting students, families and schools to better understand learning, behaviour and neurodevelopment. My assessments are evidence-based, thorough and designed to provide practical recommendations that make a difference in everyday life.
ADHD Assessments
Comprehensive diagnostic assessments for children, adolescents and adults experiencing attention, executive functioning or behavioural concerns.
Please note: I do not prescribe medication. If medication is being considered, an additional consultation with a paediatrician or psychiatrist will be required (additional cost).
Autism Assessments
Comprehensive autism assessments focusing on social communication, sensory processing and neurodevelopmental differences.
Please note: for autism funding purposes, the assessment must be conducted in person.
Behaviour Assessment and Support
Functional Behaviour Assessments (FBA) for children and young people experiencing behavioural challenges across home and school settings.
Evidence-based recommendations developed in collaboration with families and schools.
