About Illuminate
Illuminate Services

Hello, I am Dr Maria O’Neill (DClinPsych, MA, BSc Hons). I am a Clinical Psychologist registered with the Health and Care Professions Council (HCPC).

I have over 15 years experience specialising in Autism and Attention Deficit Hyperactivity Disorder (ADHD) within various settings including the NHS, private and charitable providers (National Autistic Society). I have worked within health, forensic and educational environments with involvement in the setting up of several specialist Autism and ADHD services. I currently work in a senior role within specialist Autism and ADHD services in the NHS alongside my private practice.

I have a passion in working with neurodiverse children and adults and have a positive attitude towards individual difference. I aim to offer a clear and supportive pathway for those seeking diagnosis and for those navigating life following a diagnosis. I am committed and passionate about providing a high-quality service.

I offer assessment and therapeutic support for individuals, parents and couples. My approaches include use of Cognitive Behavioural Therapy (CBT), ADHD coaching, psychoeducation, emotional toolkit, Compassion Focused Therapy (CFT) and mindfulness techniques to support individuals and their loved ones.

I coordinate independent practitioners, experienced in Autism to provide multidisciplinary team (MDT) assessment and support.

Dr O’Neill supported our daughter and us as a family through the ADHD diagnostic process with clear expertise and compassion. It has had such a helpful impact for our daughter who has described relief at feeling listened to and having her challenges understood. Thank you!

The journey for me, having been diagnosed in adulthood, has not been an easy one. However, from the first point of contact with Dr O’Neill, I felt I was benefiting from sound expertise and knowledge that has been life-changing for me in understanding my ADHD.

I like having some ideas of how to manage when I feel overwhelmed and worried. I have things to help me when I am at school and Maria helped me to understand my superpower!”
