Clare was very patient and receptive to my concerns and questions. She was very professional and respectful throughout the whole process and demonstrated empathy and understanding for my daughter’s experiences.
Clare carried out a full comprehensive MDT assessment gathering information from multiple sources and offered continued support throughout and following the assessment.
I would highly recommend Clare when considering an assessment for Autism.

Our diagnostic process

1

Initial screening

We'll check whether this service is right for you and discuss the process in more detail. 
2

Observation & case history

You will be invited to attend the clinic for structured observations and indepth discussion about your current needs and challenges.  A detailed case history will be gathered from your parent or other family member. There are alternative ways this information can be gathered if needed.  There will always be at least 2 clinicians involved in the process; one clinician will carry out the observation and a different clinician will conduct the case history.

Multidisciplinary Team Meeting

We work with a carefully-selected panel of professionals from a variety of clinical backgrounds to review our findings.
4

Sharing Our Findings

We will let you know our findings as soon as possible by phone. This will be followed by a comprehensive diagnostic report which can be presented to schools, employers or medical professionals.

I offer a caring, bespoke service that values each individual throughout the process. With decades of experience in autism diagnosis, I personally lead every assessment, ensuring a professional, high-quality service.

From face-to-face consultations to overseeing every stage of the process, I bring specialist knowledge and clinical expertise to guarantee an exceptional standard of care. With a small hand-picked panel of skilled clinicians, I ensure that every assessment is thorough, accurate, and tailored to the individual’s unique needs.

I work closely with families, schools and clinical professionals to complete a well-rounded, comprehensive assessment that considers every aspect of an individual’s needs. Autism assessments adhere to NICE guidelines – the same gold-standard framework used by the NHS – ensuring the highest level of accuracy, quality, and best practice in diagnosis. 

About Clare Williams

With over 20 years experience in autism, I’ve had the privilege of assessing more than 2,000 children, young people, and adults – including many girls, whose distinctive traits are sometimes overlooked.

My journey has taken me through specialist schools, the NHS, mental health units, and learning disability teams, giving me a deep understanding of autism.

I’ve led teams, supported families through complex cases, and provided second opinions when a diagnosis was in question. I’m passionate about ensuring that every assessment is thorough, and accurate – helping individuals and families to develop a better understanding of themselves.
