Why have an Assessment
with us?
We only use highly specialist clinicians who have at least 10 years of experience working with autistic individuals within their clinical area. We follow NICE Guidelines to ensure the assessment can be accepted by the NHS, Local Authority and Mindworks. We have a dedicated clinician who is the single point of contact throughout the assessment process. They are on hand to answer any questions that may arise and ensure a person centred, supportive service.
We offer a short free phone consultation with the Clinical Director prior to booking in for any of our assessments.
