child and adult autism & ADHD assessment

about us

Here at Pebble, we provide autism and ADHD assessments that are compliant with NICE Guidelines and accepted by schools, universities and local authorities. We started Pebble Autism in 2020 because we wanted to provide excellent quality and neuro-affirming assessments that were conducted in a way that made our clients feel safe and respected. We are a small multidisciplinary team of two highly experienced and qualified clinicians.

We are proud of the huge number of clients who have returned for second or even third (or more) assessments for family members and recommended us to their friends. We have been delighted to work with individuals and families from across the UK and overseas and honoured to provide assessments for the families of some prominent members of the autistic community.

It has always been our hope that in driving change in the more client-led way we approach assessment, without compromising on professional standards, has helped in some small way to move other services away from outdated ways of working.

Welcome to Pebble, we’d love to meet you! You can email hello@pebbleautism.co.uk or call 07816 181 810 to talk to us about your situation.

what to expect

Assessments are carried out using a combination of in-person meetings at Meet by the Park in Leamington Spa and video meetings using Teams.

Following every assessment, we will provide a detailed report. For children and young people this will include a profile of need and suggested advice and accommodations for school/college.

Adult recommendations and resources will be tailored to your individual needs.

All of the resources we recommend are created by and for autistic people and come from a strengths-based and neurodiversity-affirming perspective. We reject the ‘medical-model’ and do not describe autism as a ‘disorder’ or ‘condition’.

Everyone has the option of a follow-up session with one of the team following their assessment. There is no additional charge for this.

If you’d like to talk to us about what to expect, please email hello@pebbleautism.co.uk or call 07816 181 810. We will be pleased to answer any questions. You can also look at our FAQs about autism assessments and reports.

testimonials

  • Simply the best report (and overall experience) we have had from any professionals we have come in to contact with (and there have been many). The report is packed full of brilliant, positive and supportive advice and hand-picked neuro-affirming resources to help our family. It’s been a wonderful experience

    Parent of a 6 year old – Worcestershire

  • I have had some time now to read and absorb the report you sent me. I was impressed by how you observed and understood me and I feel that it gave a very accurate representation of who I am… and was. I had been concerned that the report may have shown my ‘performing’ self and was worried in case I had exaggerated things. This was not the case. It really did sound like me.

    Adult (59) – Bristol

  • Chris and Sue are really easy people to talk to and despite feeling nervous initially, I felt quickly at ease with them. This helped immensely throughout the assessment process. Their approach allowed me to discover my autistic identity in a positive and affirming way

    Adult (40) – London

  • I honestly didn’t believe we would get anywhere as I thought she would shut down, and I had no idea how you were going to even attempt an ADOS on a 5-year-old. You were so brilliant, and it was a joy to watch someone so good at their job – I worked in the NHS for 20+ years, and I’ve never seen anyone do such a professional, kind, engaging and thorough assessment.

    Parent of a 5 year old – Nottinghamshire

  • Our son has been using your words, and telling everyone he is ‘marvelously autistic’!

    Parent of a 13 year old – Oxfordshire

  • When you suggested we learn from the autistic community, you set our family off on a path that has completely transformed our lives and we are eternally grateful for that. The autistic advocate community I work with talk a lot about ‘ripples’ – you are both sending out some very strong, very impactful waves I’d say.

    Parent – Warwickshire

  • Irrespective of the fact that I hope one day people will no longer be ‘diagnosed’ autistic whilst we are still bound to that system I am so grateful you do it in the ‘right’ way. A way that validates and celebrates the child in front of you and shields families from much of the harmful and incorrect narrative.

Adult Autism Diagnosis

I was recommended Pebble Autism by my university and I would absolutely recommend them to anybody looking for an autism diagnosis for themselves or their family. Chris and Sue were able to turn what could have been a stressful process into a positive, informative and helpful experience. Pursuing a diagnosis as an adult, I had many concerns going into this about masking, having enough evidence from childhood etc, but Chris and Sue were nothing but supportive the entire time. I also appreciate the diagnostic report which included a long list of resources and information to help me in the future.

Pebble Autism – 5 Stars

I chose Pebble Autism as I had previously worked at the same school as Chris and liked his approach with and respect of the students. I was initially nervous about embarking on the assessment process, but both Sue and Chris made it very straightforward and I felt supported throughout. I felt truly listened to, even when I was trying to formulate answers to questions I was finding difficult. Their relaxed and professional approach made the process easier. I would, therefore, highly recommend Pebble Autism.

From our initial meeting with Sue setting the tone for a relaxed and a professional understanding.This quickly became a positive experience.Sue was engaging to talk to making the process very comfortable . This initial meeting soon became a natural conversation. This warm approach continued throughout the assessment with Chris showing expert and inspiring enthusiasm to engage with our child.
