Neurodiversity-Affirming

I don't see neurological differences as deficits — I see them as variations in how people process, relate, and engage. The work is built on understanding your strengths.

Rare Dual Expertise

Licensed Clinical Psychologist (PSY35915) and Board-Certified Behavior Analyst (BCBA) — a combination that gives a uniquely comprehensive lens on how people think, feel, and function.

Truly Individualized

No two brains are the same. Every evaluation I conduct and every therapy plan I design is built from the ground up for that specific person. There is no template.
