Our story
Our story
Hillcrest Neuro Clinic was established to address a critical gap in mental health services: the need for specialist, accessible ADHD assessments that don't compromise on quality or compassion.
Founded by Walter M Tavaziva, a Registered Manager and Senior ADHD Practitioner with over 20 years of clinical experience, Hillcrest brings together a multidisciplinary team of specialists committed to delivering thorough, evidence-based assessments.
We believe that understanding your neurodevelopmental profile is the first step towards meaningful change — and we're here to guide you through every step of that journey.
Clinical excellence
Every assessment follows gold-standard protocols including DIVA-5 and ADOS-2, delivered by fully qualified practitioners.
Person-centred care
We take time to understand your unique circumstances, ensuring assessments are thorough, unhurried, and compassionate.
Transparency
Clear pricing, honest timelines, and straightforward communication — no surprises, no hidden costs.
Continuity
From initial assessment through to treatment and ongoing support, we're with you for the long term.
