I’m excited to officially launch this page and share my work supporting children, teens, adults, and their families. As a licensed psychologist and certified school psychologist, I provide evidence-based CBT therapy and comprehensive psychological evaluations, including assessments for ADHD, learning differences, and Autism Spectrum Disorder.

My goal is simple: to offer clarity, support, and practical tools that help individuals better understand themselves and thrive—at home, in school, and beyond.
