I provide comprehensive psychological evaluations for children ages 3+, teens, adults, and older adults. Maybe your child is struggling at school and you’re not sure why. Maybe you’ve wondered for years whether ADHD or autism could explain things that have always felt harder for you than they seem to be for others. Or perhaps you or someone you love is experiencing changes in memory, attention, or thinking. My goal is to help you move from questions and uncertainty to a clearer understanding of how you think, learn, feel, and function, and what can help you move forward.

I specialize in psychological and neuropsychological assessment, including autism, ADHD, learning disorders, intellectual disability, FASD, traumatic brain injury, cognitive decline, and complex mood, anxiety, and personality concerns. Evaluations are individualized, including clear findings and practical recs you can use at work, school, or w/ your provider

Seeking an evaluation can feel like a big step, especially after years of wondering or searching for answers. My approach is collaborative and strengths-based. My goal is to offer more than a diagnosis. It is to help you understand yourself or your child, find meaningful answers, and leave with a clear path forward. I welcome you to reach out.
