About

Our Story

A More Inclusive Approach To Therapy

Onyx Therapy was founded by Occupational Therapist Justine McDonnell and Speech & Language Therapist Maddisyn English, two neurodivergent clinicians who shared a vision for doing therapy differently.

Throughout our careers, we saw too many neurodivergent individuals being misunderstood, expected to fit into environments that didn’t work for them, or offered support that focused on changing who they were rather than understanding what they needed. We knew there had to be a better way.

Years Experience

Drawing on both professional expertise and lived experience, we created Onyx Therapy to provide neuroaffirming support that recognises and celebrates individual differences. We believe that neurodivergent people do not need fixing. Instead, they deserve understanding, acceptance, and the right support to thrive as their authentic selves.

Today, we work with children, young people, adults, families, schools and organisations across the UK, providing Occupational Therapy, Speech & Language Therapy, training and consultancy. Everything we do is guided by our commitment to creating meaningful change, empowering self-understanding, and helping build environments where people can flourish.

Our Purpose & Direction

At Onyx Therapy, everything we do is guided by a clear commitment to champion neurodiversity, dismantle stigma, and ensure every individual we work with feels genuinely understood, valued, and supported.

Motto

Neurodivergent therapists supporting neurodivergent clients.

Purpose

To empower neurodivergent individuals, their families, and the people who support them through neuroaffirming, evidence-informed therapy that creates meaningful and lasting change.

Direction

To shape a future where neurodivergent people no longer need to mask, fit in, or justify their differences in order to access opportunities, belonging, and success.

Our Values

Because we know that feeling understood can make all the difference.

Neuroaffirming

We recognise neurodiversity as a natural part of human variation. We focus on understanding and supporting individual differences rather than changing who someone is.

Authenticity

We encourage people to be themselves without shame, masking, or pressure to conform to expectations that do not serve them.

Collaboration

The people we support are experts in their own experiences. We work alongside individuals, families, schools, and organisations to create meaningful change together.

Curiosity

We seek to understand before we seek to solve. We value listening, learning, and exploring each person's unique strengths, challenges, and experiences.

Practical Impact

We focus on strategies and solutions that make a genuine difference in everyday life, supporting participation, independence, wellbeing, and quality of life.

Courage

We challenge outdated thinking, advocate for inclusion, and use our voices to drive positive change within therapy, education, and the wider community.
