My Ideal Client

I work with children, teens, and adults seeking clarity through psychological testing for autism, ADHD, and learning differences. Many of my clients are bright, capable individuals who have long felt unseen or misunderstood. I specialize in high-masking females, transgender, and gender-diverse clients, providing neurodiversity-affirming evaluations that validate their experiences and uncover strengths. I proudly serve clients throughout the Portland metro area.

What I Specialize In

I’m a licensed clinical psychologist with advanced training in psychological and neurodevelopmental assessment. I earned my Doctor of Psychology from Pacific University’s APA-accredited program, where my dissertation focused on transgender and gender-diverse youth. Over the years, I’ve conducted hundreds of comprehensive evaluations for autism, ADHD, learning disorders, and intellectual disabilities across children, teens, and adults. My background includes experience at the Children’s Program, NW ADHD Treatment Center, Providence Children’s Development Institute, and Legacy Medical Center’s Transgender Youth Assessment Team. I specialize in identifying autism in adult women and AFAB individuals, high-masking presentations, and co-occurring ADHD. My evaluations are neurodiversity-affirming, strengths-based, and collaborative, helping clients gain clarity, confidence, and self-understanding. I offer one-day, in-person evaluations from my office in the greater Portland, Oregon area.

My Personal Beliefs and Interests

I believe that every person deserves to feel understood, validated, and celebrated for who they are. My work is grounded in a neurodiversity-affirming and LGBTQ+ affirming approach, valuing the unique experiences and strengths of each individual. I’m passionate about creating a safe, welcoming space for clients of all gender identities, neurotypes, and backgrounds. My doctoral research focused on supporting transgender and gender-diverse youth, and I remain deeply committed to advocacy for inclusive, affirming care in our community. Outside of my professional life, I love spending time outdoors, exploring Oregon’s natural beauty, and relaxing with my partner and our cats. My goal, both personally and professionally, is to help others feel seen, empowered, and confident in who they are.
