At 305 Brains, I specialize in understanding how the brain shapes behavior, emotion, and everyday functioning. As a licensed clinical neuropsychologist, I provide comprehensive, evidence-based evaluations to help clarify diagnoses and guide meaningful next steps for both children, adults, and seniors.
Many of the individuals and families I work with come in feeling overwhelmed, confused, or unsure of what’s really going on. Whether you’re navigating concerns related to ADHD, autism, learning differences, brain injury, dementia, or changes in thinking and behavior, my goal is to provide clarity, not just a report.
Neuropsychology is a diagnostic tool utilized to provide a clear path for rehabilitation, confidence, and improving quality of life.
As a TBI survivor, I understand the process of waiting for a diagnosis and seeing results. The hardship of spending time & money in neuropsychological assessments can be draining, I try to make the process as pleasant as possible for my patients.
