kathKathleen has spent 14 years building a strong understanding of the Autism Spectrum (ASD), while also gathering skills in Clinical Psychology and Organisational Psychology. She has maintained her focus on ASD and worked alongside colleagues with great knowledge of ASD such as Professor Tony Attwood. This combination has led to demand for not only providing individual and couples based consultation, but also dynamic training/workshop events, team management, and international business development for autism intervention. Kathleen holds a particular interest in assisting with ASD and legal issues – criminal, family and civil law. Her interest led to membership of the editorial team for the Journal of Intellectual Disabilities and Offending Behaviour, co-chair of the first International Meeting For Autism Research (IMFAR) Forensic Special Interest Group, and supported forensic case work with international ASD expert, Professor Gary Mesibov. Having experience working within the police service, child and family services, and organisational health services, Kathleen is unique in her ability to work in a specialized way with professionals and clients with ASD around issues involving interactions with the criminal justice system, family separation, and workplace dynamics. For the past 4 years, Kathleen has provided face-to-face clinics in Brisbane and Mackay while providing tele-health options for other locations. In addition to Decipher Zone, Kathleen is Principal Consultant at the Social Skills Training Institute, a subsidiary of the Cooperative Research Centre for Living with Autism Spectrum Disorders (Autism CRC). Kathleen works here with Dr Renae Beaumont, distributing and training professionals internationally to deliver the Secret Agent Society program for children with high functioning (Asperger type) ASD.
