Who is Will Barker?

At Will Barker Assessments, we understand that today’s world can feel overwhelming for neurodivergent children and young people. Before assessment and intervention, many struggle silently with challenges that others cannot see—sensory overload, emotional dysregulation, social confusion, academic pressure, or the exhausting effort of masking their difficulties. These experiences can lead to frustration, anxiety, and a sense of being misunderstood. Families often know their child is capable and bright, yet without clarity or support, everyday life can feel far more difficult than it needs to be. This is where specialist, compassionate assessment makes all the difference.
Will Barker is a Nursing and Midwifery Council registered Mental Health Nurse, specialising in the assessment of Autism and Attention Deficit Hyperactivity Disorder (ADHD). With over a decade of experience in mental health and neurodevelopmental practice, Will brings a rare combination of clinical expertise, therapeutic skill, and genuine understanding of the lived experiences of neurodivergent young people.
Will is trained and qualified in delivering gold-standard diagnostic tools, including:
-
