About Us

What we do

We are a Multi-Disciplinary Team of experienced professionals providing a timely private Autism Assessment and Diagnostic Service for young people aged up to 18 years old. Our team is made up of a Paediatrician, Specialist Speech and Language Therapists and a Specialist Clinical Psychologist. We each work jointly in the NHS and as Private Providers. Our aim is to ensure Families have rapid access to our assessment process with provision of our detailed diagnostic report outlining the Young Person’s strengths, weaknesses and recommendations of how they may best be supported. We passionately believe in helping improve awareness of Autism Spectrum Disorder and ensure a thorough assessment is completed in adherence to current NICE Guidelines to enable families to access the most appropriate support for their child. As a team we also feel it is important to remember the positive attributes those diagnosed with an Autism Spectrum Disorder possess and consider the positives from Neurodiversity as well as the significant difficulties that may occur in an individual.
