About Christa Stow Hill, M.A.
Christa Hill is a Psychology Associate at Orchard Mental Health Group, focusing exclusively on psychological and neuropsychological assessments for children, adolescents, and adults. Whether you’re exploring questions related to autism or ADHD, preparing for a surgical procedure (such as bariatric surgery or a spinal cord stimulator), facing memory or cognitive concerns, or seeking diagnostic clarification, Christa offers thorough, respectful, and neurodiversity-affirming evaluations.
Christa works collaboratively with clients, families, and multidisciplinary teams to translate complex assessment findings into clear, actionable insights. Her approach recognises that assessment isn’t about labelling, it’s about understanding how you think, feel, and function in the world.
