A Bit About Me

I’m Dr. Marissa Miller, a licensed psychologist specializing in neurodivergent-affirming assessments. My extensive experience spans hospital, school, and clinic environments, all unified by a focus on neurodiversity. I find great joy in working with youth and families to uncover their unique contributions to our neurodiverse community and collaboratively identify supports tailored to their specific strengths and needs.

I understand that psychological and psychoeducational evaluations are significant and impactful milestones for families. Therefore, I adopt a collaborative approach throughout the process. There are often multiple effective pathways to achieve a goal, and I believe in working together to identify the best options at each stage of the evaluation. Our journey begins with a discussion of your goals for the assessment and devising a plan to achieve them. From the initial intake call to the final feedback session, I strive to create an environment where my clients and their families can be their authentic selves. While diagnoses can be part of the process, they are not my primary focus. I aim to understand clients as they are now and help them celebrate and advocate for themselves in meaningful ways.

I enjoy reading non-fiction, exploring nature, and appreciating the arts in my free time. I also love hearing about the interests and passions of my clients. There is always more to learn and room to grow.
