Whiz Kids provides speech therapy and assessment services that puts your child and family first.



Because Whiz Kids Therapy is committed to supporting your child to reach their potential, we provide speech therapy and assessment services that are evidence-based and well-regarded within the profession.  Our speech pathology services are based on

"...The conscientious, explicit, and judicious use of current best evidence in making decisions about the care of individual patients....integrating individual clinical expertise with the best available external clinical evidence from systematic research.” (Sackett et al, 1996)



Whiz Kids speech therapists all hold Masters or Bachelor degrees in Speech Pathology, have current Working with Children checks, and have completed a First Aid Course. Your speech pathologist maintains Certified Practicing Speech Pathologist (CPSP) status - this certification is given to a speech therapist by our professional body, Speech Pathology Australia, to demonstrate to clients, their families, and the public, that your speech pathologist has an ongoing commitment to improving their professional knowledge and skills. Whiz Kids Therapy is committed to keeping up with the latest research, and are engaged in continuing professional development.



Whiz Kids Therapy is a family centred speech pathology practice. This means that the aspirations, needs and concerns of the family informs and directs the goals for speech pathology assessment and intervention. The relationship between the child, family and therapist is collaborative - Whiz Kids provides support that is individualised, flexible and responsive to your family's needs. Family participation and involvement is actively encouraged - you will be involved in planning of speech, language and literacy goals, and kept abreast of the progress your child is making.
