Who will my child see?

When you ring to discuss an assessment, we will discuss your concerns on the phone and then book an appointment with one of our therapists.  Who your child sees will depend on:

  • Best therapist to see your child.  
    While our therapists cover all areas of communication and learning, some of us have more specialisation in certain areas. We will recommend that therapist for your child.
  • Appointment times that are available to suit your timetable
