Adult ADHD & Autism Assessments for People Seeking Clarity and Answers

Comprehensive Online Assessments With A Clinical Psychologist Who Understands Late-Identified, High-Camouflaging Presentations & Neurodivergent Experiences Across Adulthood.

Welcome - I’m Catherine Eliot

I am a Perth-based Clinical Psychologist providing Australia-wide ADHD and Autism online assessments.

I am particularly drawn to supporting individuals whose experiences may have been overlooked or misunderstood, including those with more internalised or high-masking presentations. Many of the people I work with are insightful, capable, and deeply self-aware, yet have spent years navigating challenges that haven’t always been recognised or accurately explained.

Alongside my clinical training, I also bring personal insight into late-diagnosed ADHD, which informs a deeper appreciation of the more nuanced and often less visible ways it can present in Women & in adulthood. This perspective supports me to approach assessments with both clinical rigour and genuine understanding, particularly for those who may not identify with more traditional or externalised presentations.

My approach to assessment is thoughtful, thorough, and collaborative. I aim to create a space where you can feel at ease and able to be yourself, without needing to mask or “fit” a particular expectation.

The process is designed not only to assess for diagnosis where appropriate, but to offer meaningful insight into how your mind works, including both strengths and areas of difficulty.

My approach is warm, practical, and grounded in both lived experience and evidence-based practice.

Services are provided online via secure videoconferencing for adults Australia wide.
