Motivated by their commitment to promoting neurodiversity and challenging societal misconceptions, Maddi and Justine, co-founders of Onyx Therapy, embarked on the journey of establishing their private therapy business. They recognised the need for a more inclusive approach and envisioned a space where individuals could access personalised and empathetic care without the burden of neurodivergence stigma. Fuelled by their collective expertise and dedication to embracing diverse neurological experiences, they sought to build a practice that prioritises individual needs, fosters a strong therapeutic alliance, and employs innovative approaches to ensure holistic well-being for every client. Maddi and Justine believe in the transformative power of a neurodiversity-affirming approach and are dedicated to providing a safe haven for personal growth and support.

Maddi
Hi, I’m Maddisyn (Maddi) English, a speech and language therapist and co-founder of Onyx Therapy. I have extensive experience working with a wide range of people with Autism, as well as a passion for delivering relevant training to patients, family, teachers, carers, and workplaces on various diagnoses and their impact on day-to-day functioning. Since graduating with a Bachelor of Speech Pathology from Southern Cross University, Australia, I have gone on to work in hospitals and educational settings on both sides of the globe. I have undertaken placements at Innisfail Hospital and Ipswich Hospital in Australia, worked at Brisbane Catholic Education (a network of 141 schools in Australia), and since moving to the United Kingdom, I have worked as a speech and language therapist at a specialist Autism Spectrum Condition school.
I enjoy working closely with clients and their families to help ensure the best possible care and support throughout their treatment journey. I recognise the diversity within neurodivergent experiences, and am committed to providing tailored support that goes beyond conventional methods. My practice adopts a neurodivergent-affirming approach which celebrates the unique strengths and communication styles of each individual, fostering an environment where differences are not only acknowledged but valued. Through collaboration and respect, I strive to create a space where clients feel understood and empowered.
Currently I am working on peer reviewing a book on gestalt language processing (GLP) , alongside my day-to-day responsibilities as a therapist, which also involves providing supervision needs to fellow colleagues and co-teaching core subjects such as Maths and English.

Esme Naylor
Hi I’m Esme, I am a Therapy Assistant and a proud member of the Onyx Therapy team. I have 4 years of experience working within the mental health field and a lifetime of experience living as a part of a neurodivergent family, giving me a unique perspective of neurodiversity. I especially believe in the importance of neuro-affirming practice, because I am aware of the frustration of being told that the way you are is “wrong” and others trying to “fix” you. I believe differences should be celebrated, and I know that neurodivergent individuals can thrive when supported in a way that makes sense to them, even if it doesn’t make sense to someone who is neurotypical.
I worked for 3 years in the NHS on an acute female inpatient mental health ward, where many patients were neurodivergent. I then moved to the community for a year, where I worked with clients diagnosed with ASD. I am currently studying Counselling Skills, CPCAB membership awarded on completion.

Hi, I’m Justine McDonnell, an occupational therapist and co-founder of Onyx Therapy. I am a dedicated Lead Occupational Therapist and Advanced Sensory Integration Practitioner with a proven track record of over a decade in providing specialised care and support to individuals with diverse needs.
My journey began with a focus on personalised technology coordination at Hft, where I assessed individuals with learning disabilities to identify and implement assistive technologies, empowering them to lead more independent lives. This experience laid the foundation for my subsequent roles, where I transitioned into leading Occupational Therapy services and integrating sensory approaches to support students with autism in a special school environment.
I am a passionate advocate for neurodiversity, celebrating the strengths and unique perspectives that each individual brings. With a deep understanding of the diverse ways people experience the world, I aim to foster an environment that embraces differences and empowers clients to navigate the world in their own authentic way.
