ADHD UK Ambassador

Justine McDonnell

Late diagnosed ADHDer and Therapy business owner

I'm Justine, a late-diagnosed ADHDer, Occupational Therapist, and co-founder of Onyx Therapy – a neuroaffirming practice supporting neurodivergent children, young people and adults across the UK.

For years, I worked alongside neurodivergent young people, completely unaware that I was navigating the world with an ADHD brain too. Receiving my diagnosis later in life was validating, transformative and, in many ways, helped me make sense of myself. It also strengthened my passion for advocating for better understanding and support for neurodivergent people.

Through my work at Onyx Therapy, I'm passionate about helping people understand their neurodivergence without automatically viewing difference as a deficit. I believe we need environments and systems that recognise different ways of thinking, communicating, regulating and participating – rather than continually expecting neurodivergent people to adapt themselves to fit.

As an ADHD UK Ambassador, I'm particularly passionate about changing the conversation around ADHD for those who have historically been missed or misunderstood, including women, professionals and people diagnosed later in life.

I want to use both my lived experience and my clinical experience to raise awareness, challenge stigma and advocate for ADHDers to have access to understanding, appropriate and neuroaffirming support at every stage of life.

I'd love to help create a world where ADHDers don't have to spend years wondering why things seem harder for them – but instead have the understanding, language and support they need to understand their own brains and thrive as themselves.
