About Us

We are a small team of clinicians who are very experienced working with people with ASC across the lifespan. The team is made up of Clinical Psychologists, Speech and Language Therapist and an Assistant Psychologist. We are all trained and experienced in the assessment tools that we use. We are also registered with relevant professional bodies.  We are friendly and professional and frequently get feedback on how we managed to make people feel at ease during the assessment process.

 Dr Andrew Parkinson has been of invaluable help for my adult son. 

To go through an ASD assessment in your late twenties can be a very, very difficult experience; but thanks to Andrew's relaxed and empathetic communication style my son was very reassured. 


Andrew has helped us, as a family, turn this experience into a very positive step into a better future for my son. Highly recommended!

Dr Andrew Parkinson has a very friendly, personable, and professional approach to his work.


He assessed my son and my daughter, diagnosing them both with ASC (Autism Spectrum Condition). 


Dr Parkinson and Esther Hiley have a natural ability to put children at ease and gain their trust, thereby enabling them to accurately and efficiently go about their work in a calm, pleasant manner. 


Whether assessing and diagnosing adults or children, their open and affable demeanour allows for a comfortable and relaxing setting, so that the process runs smoothly and reassuringly.


We are very grateful to the team for the help they have given to our family"

Parent of 2 children who were assessed

Sterling service. Highly recommend Dr Andrew Parkinson and the team at Sussex Autism Assessments. Liberating to be understood. His astute perception of needs ensured that the assessment was conducted tailored to me, as needed. That takes patience, understanding, sensitivity and skill.

His thoroughness and professionalism coupled with his calm, kind manner delivered a service which can only be described as generously accommodating. He has a wonderful combination of professionalism and humanity, which instilled confidence in what is a sensitive assessment process. Thank you so very much.

Adult Female who was assessed

I cannot rate Sussex Autism Assessments highly enough. The assessment they carried out with my child was thorough and we were kept well informed throughout the whole process. We did not feel rushed and felt listened to - Andrew's support and advice has been invaluable.
