About Us

Our Team

OneOnOne Children’s Therapy offers Speech Pathology, Occupational Therapy and the Early Start Denver Model (ESDM). We are an early intervention clinic in Bondi Junction, in Sydney’s Eastern Suburbs. OneOnOne Children’s Therapy has been offering private intervention services for over 33 years (previously known as Time To Talk). We work with young children who have autism and developmental delay. We also work with school aged students who are having difficulty with literacy, spelling and writing. We recognise that each is unique and has his or her own needs, wants and challenges. By offering an interdisciplinary approach, our highly skilled therapists work with you and your child in a holistic way to deliver evidence based intervention.

OneOnOne Children’s Therapy offers the following interventions in our Bondi Junction clinic:

  • Speech Pathology 
  • Occupational Therapy
  • Early Start Denver Model (ESDM)
  • Sounds Write
  • Feeding Clinic
  • Augmentative Alternative Communication (AAC)

OneOnOne Children’s Therapy is committed to quality, extensive staff training evidence based interventions. Our staff are highly skilled in their areas of intervention. We are able to do this through frequent in-house training, having experts in the field come into the clinic regularly to maintain staff fidelity in intervention approaches, and external attendance at professional development events. Our aim is to provide therapy that will enable the children to achieve their full potential in every aspect of their lives.

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, motor development and learning, some of us are specialised in certain areas. We will recommend that therapist for your child.
  • Appointment times that are available to suit your timetable
