Arkadia Clinic is a specialist neurodevelopmental assessment and support service. We provide high-quality ADHD and Autism Spectrum Disorder assessments and diagnostic services, helping children, young people, and adults gain clarity, understanding, and access to the support they need. At Arkadia Clinic, we believe diagnosis is only the beginning. Thrive Beyond provides compassionate, neuroaffirming support that empowers individuals and families to build confidence, improve wellbeing, and flourish in education, work, and everyday life. Our ADHD and Autism service provides expert outpatient clinics and specialist neurodevelopmental assessments, supporting the NHS in managing the growing demand for timely assessment and diagnosis across both adult and paediatric populations. We deliver fully managed insourced services within NHS settings, working in partnership with healthcare systems to provide efficient, high-quality care that reduces waiting times while maintaining clinical excellence. Our insourced model integrates seamlessly with existing pathways, enabling Trusts and services to expand capacity without disruption. In parallel, we offer private assessment and diagnostic services through Arkadia Clinic, providing individuals and families with greater flexibility and faster access to support outside of NHS waiting lists. These services mirror the same high clinical standards and can support continuity of care where appropriate. Across both pathways, our focus is on delivering accessible, compliant, and patient-centred neurodevelopmental services that support both immediate demand and long-term service sustainability.
