Castle Hill Speech & Occupational Therapy

Dedicated to supporting your child with the best evidence based therapeutic interventions.

We help your child find life changing confidence

At our practice we support children and teenagers in a family friendly setting, using bespoke treatment plans and therapies with a multidisciplinary input.

Getting started is as simple as...

15 Minute Call


A 10 – 15 minute phone consultation aimed at providing the best advice as to which service/assessment is required.

Formal Assessment


A formal assessment is then booked in. Once the assessment is completed, a written report will be provided within 2 weeks.

Therapy Sessions


Therapy options are then discussed and, if required, liaison with school/preschool and other professionals is initiated.

“Children with autism are colorful – they are often very beautiful and, like the rainbow, they stand out.”

We're a family

Our aim is to create a sense of family that feels just like home.

Areas of focus

Speech Pathology

Communication is a critical skill for all children and teenagers. It’s a key requirement for playing, learning and establishing friendships. It's a skill that your child will use throughout their life.

Early identification and intervention for communication difficulties will make a significant impact on your child's development. Our goal is to assist your child to communicate as effectively as possible across all environments.

Occupational Therapy

Children’s lives are comprised of playing, learning and making friends. To confidently be able to engage in these activities a child requires appropriate fine motor, gross motor, visual perceptual skills, sensory and processing skills.

This is what we focus on with occupational therapy. Our goal is to enable your child to participate in all activities as confidently as possible.

Music Therapy

Music therapy is an evidence based clinical use of musical intervention to improve quality of life. Research has shown that music therapy improves speech, communication and social skills.

Research also connects music therapy to improved bodily movement, co-ordination and function; as well as imporved memory, attention and brain power.

Behaviour Therapy

Behavior therapy seeks to identify and change potentially negative /unhealthy behaviors. It functions on the idea that all behaviors are learned and that unhealthy behaviors can be changed.

Autism Assessments

Current research suggests that the earlier a child is accurately diagnosed with ASD and begins affective therapy and interventions, the better the developmental outcomes for the child. Diagnosis of ASD requires a comprehensive assessment progress. It includes gathering information from a range of sources, typically an interview with a parent, observing the child in their home and/or at school.

At our practice we offer a comprehensive assessment for ASD which involves:

- the Autism Diagnostic Observation Schedule – Second Edition (ADOS-2), which has been rated as the most reliable diagnostic tool recognised by international ASD experts

- the Autism Diagnostic Interview – Revised (ADI-R) which is a structured parent interview that assists in the reliable diagnosis of ASD

- parent rating & observation scales

- detailed speech pathology assessment

- detailed occupational therapy assessment

These are chosen according to your child’s age and developmental levels.
