Services
ADHD Assessments
Our ADHD assessments combine parent interviews, clinical observations, and standardised tests to evaluate attention deficits and hyperactivity. We use tools like the Wechsler scales and behavioural checklists to create comprehensive profiles. Results inform tailored intervention strategies for home and school environments.
Autism Diagnosis
Autism Spectrum Disorder assessments involve developmental history reviews, direct observation, and specialised tools like the ADOS-2. We evaluate social communication skills, repetitive behaviours, and sensory sensitivities to provide accurate diagnoses and support recommendations for families and educators.
Educational Testing
We conduct comprehensive educational evaluations measuring intellectual ability (WISC-V), academic achievement (WIAT-III), and cognitive processing. These assessments identify learning disabilities, giftedness, and academic strengths/weaknesses to develop targeted educational strategies and support plans.
Psychological Treatment
Our evidence-based treatments address anxiety, behavioural issues, and emotional difficulties using programs like Cool Kids and Anger Busters. Therapy combines parent involvement, skill-building exercises, and school collaboration to create lasting positive outcomes for children and families.
Developmental Screening
Developmental assessments for preschoolers evaluate motor skills, language development, and social-emotional functioning. Using tools like the WPPSI-IV, we identify delays or giftedness in children aged 2-7 years to guide early intervention and educational planning.

This was the first time I had one of my children assessed and I wasn't entirely sure what to expect but the team was fantastic and my child had such a positive experience. They were warm yet professional and all their work was done in a timely manner.

Report
I went here for a test for dyslexia. It cost $800 and I received no report and no reembursement from my health provider.

Report
We came to here for help with teen anxiety and the staff were fantastic. They really know how to talk to a child this age and they provided strategies that worked in practice rather than just theory. I couldn't recommend them more highly.
