OCD, ADHD, and Autism Therapy in Portland, Oregon

Neurodivergent-Affirming Therapy for Adults & Teens

Meet your therapist & resident nerd.

Hey! I’m Cassandra Miasnikov, an LGBTQ+ neurodivergent therapist based in Portland, Oregon. I was diagnosed with ADHD & autism spectrum disorder as a teen, and I know it’s not easy living in a world that wasn’t designed for you.

No one should have to figure everything out alone, or spend years getting brushed off by providers working from outdated models.

I specialize in OCD, ADHD, and autism, especially people of color, women, nonbinary, and trans clients who don’t fit “traditional” clinical profiles.

I’ve presented at conferences including the International OCD Foundation (IOCDF) and NAMI, and have written on mental health for Business Insider and the International Bipolar Foundation.

Therapy with me is collaborative, practical, and grounded in ACT, CBT, DBT, and ERP.

 

Shame-Free Therapy.

Together, we create a therapeutic space that honors your individuality, supports growth, and builds resilience without shame.

Rather than focusing on what’s “wrong,” we’ll identify your strengths and support needs.

Therapy is a partnership; we’ll build skills, celebrate successes, & help you achieve your goals.

Based in Portland, Oregon, I offer telehealth therapy to clients across the state.

I work with neurodivergent individuals, couples, and families, specializing in OCD, ADHD, and autism. My approach is grounded in evidence-based therapies, including Exposure and Response Prevention (ERP) for OCD.
