Psychology & Professional Services
I create a supportive environment that fosters growth and success. Let me help you or your organisation navigate challenges and unlock your full potential.​
I provide accessible ADHD and Autism assessments using the DIVA-5 and MIGDAS-2 for adults in collaboration with psychiatrists and GPs. Every assessment is neurodiversity-affirming and designed to provide both validation and direction, while also giving you and the people around you the language, evidence, and strategies needed to better support your wellbeing.
I offer Fitness to Work and Return to Work psychological assessments. These services are crucial for informing decisions in complex cases, particularly those managed under Workers' Compensation (WorkCover), Motor Vehicle Accident (CTP) claims.​ My focus is to provide clients with a clear, objective assessment of an individual’s psychological readiness and functional capacity to perform their job duties following an injury, illness, or period of absence safely and sustainably.
I conduct independent psychological assessments for medicolegal uses. My reports address workplace psychological injury, neurodevelopmental conditions, complex trauma, and fitness to work, and are prepared to assist courts, tribunals, and decision-makers with objective, evidence-based psychological opinion. Referrals are accepted directly, through MeDirect, from both plaintiff and defendant solicitors, insurers, and employers.
​
What steps is your organisation taking to design and implement effective psychosocial risk management systems in response to this clear regulatory and legislative intent?
Using my evidence-based diagnostic tools, Behavioural Edge Psychology assesses psychosocial risks and provides actionable recommendations. This helps organisations not only comply with regulations but also achieve best-practice standards.
​
Career coaching at Behavioural Edge Psychology is led by Mark Fischer, a senior leader with more than a decade of experience across higher education, state government, executive search, and innovation. The service offers a structured space to think through a career question with a coach who has worked on both sides of the table, hiring senior people, leading large teams, and partnering with executives through significant change.
