About Autism Consultants

John Forrester is a specialist autism consultant based in the North East of Scotland. He has been involved in the support and assessment of individuals with ASD since 1991, working exclusively with people with ASD since 1996. During his training and development he has completed a degree in Autism (adults) and has developed assessment expertise in his collaborative work with NHS, voluntary sector, local authorities, and people and families affected by ASD.

Although interested in variety of matters related to ASD, John's special interests are in diagnosis of ASD (adults particularly) and forensic issues in ASD. Since 2003, he has been involved in the diagnostic assessment of several hundred adults with suspected ASD, working closely with NHS departments in this developing  area within adult mental health and learning disability services. John has also undertaken assessment of behaviour, needs and risk with many individuals with ASD during his career, and continues to work closely with the courts, police, and legal departments - providing formal assessment of risk (or otherwise) upon request.

During his employment with Grampian Autistic Society, John's role developed to that of Training & Assessment Consultant. He has delivered a variety of ASD related consultancy and training courses, awareness sessions, and presentations; to conferences, agencies and organizations across Scotland.
