Hello and welcome

I’m Dr Hilary Dyer, Writer, Psychologist and PDA Guru, based near York in the UK.

I now focus exclusively on researching and writing about PDA.

I no longer offer clinical assessments for PDA as a Specialist Consultant Educational Psychologist. This has been the focus for my independent practice for the last 15 years. From it I have generated considerable knowledge and insights into PDA.

My forthcoming book draws on my extensive clinical practice over the last 15 years, within the specialist area of Pathological Demand Avoidance -PDA. This is a sub-variant of the Autism Spectrum. To find out more about PDA click here.

We had A’s tribunal yesterday. We won (got what A is legally entitled to) and mostly got everything in his education package which A needs. We honestly can’t thank you enough for your amazing report and the preparation and care you put in that meant A could engage and you give such thorough recommendations. We were elated yesterday – as was A. He said ‘I’m free!!’ when we told him. Thank you again Hilary.

Dear Hilary I just wanted to say a huge thank you for recommending Dr Daniel Weisberg. He came down from Manchester to Southend to carry out a full cognitive assessment of U - it took six hours over two days but thanks to his enormous skill, patience and compassion he managed to do it. (By way of contrast, the local authority's EP gave up after 10 minutes!) His extremely helpful report is now being considered by the EHC assessment panel. So thank you once again for the recommendation and all your other suggestions, they have been invaluable. Best wishes J

Oh Hilary - thank you so much. I can't express in words how important what you have done for families like ours is. I will never forget the moment we spoke on the phone for the first time and how it felt to speak to a professional who just totally got it. I literally came off the call, cried and then called my Mum to tell her I had found my (and A's) tribe. Your report is beyond anything we could have imagined.

Dear Hilary, Thank you for sending your report - we couldn’t be more grateful for the care and attention you have taken to understand T and what she needs. It is hard to read some of the information it contains, but it is also empowering to experience your validation of her unique set of strengths and challenges.

Hilary, your report is a real testament to your dedication to ensuring children (and families!) living with PDA, are much better understood. We are confident the report will go on to have a tremendous impact. After your efforts during some long and difficult months here, we are feeling very grateful (and relieved) to be able to return to tribunal in April much more reassured of our position.
