Why families choose Thrive

Most ABA looks the same on paper. What makes Thrive different is the way we actually show up. Naturalistic teaching that respects how your child plays and learns, a BCBA you'll recognize by name, and schedules that bend around your family's real life, not the other way around.

We're small on purpose. That means every family gets a clinical lead who knows your child's history, your goals, and what "a good day" looks like for you.

What we do

In-Home ABA Therapy

1:1 sessions in the environment your child is most comfortable in. We bring the structure; your home stays your home.

School & Community Support

Behavior support inside the classroom or out in the world, at the park, at grandma's, at the grocery store. Skills generalize where life happens.

Social Skills Training

Evidence-based group and 1:1 social skills work that helps kids build friendships, regulate big feelings, and feel confident around peers.

How it works

Free 15 minute consultation

We listen. You ask anything.

Assessment & treatment plan

Tailored to your child, not a template.

Therapy begins

Most families start within 2-4 weeks of first call.

Founder Spotlight

Sivan So, BCBA, M.Ed., LBA

Hi, I'm Sivan So, BCBA. I'm a University of Washington graduate with a Master's in Applied Behavior Analysis and over a decade of experience working with children, teens, and adults on the autism spectrum. I started Thrive because I wanted to do this work the way it should be done, small caseloads, real relationships, and a relentless focus on the skills that actually change a family's day-to-day life.

Ryan Selberg BCBA, M.Ed., LBA

I'm Ryan, and I've spent over a decade in the field because I genuinely love it. I'm a UW-trained BCBA with a Master's in Applied Behavior Analysis, but what I'm most proud of is the kind of clinician I've become, someone who takes the time to actually know the kid in front of me, not just the goals on paper. I believe the best therapy happens when a child feels safe, and when parents feel like real partners in the process.

Parent of a 16-year-old in South Sound

“Before starting services, we were overwhelmed and unsure what to expect. The team helped us understand the process clearly and made everything feel manageable. We started seeing improvements in his communication and daily routines within a few weeks, and we finally felt like we had a clear plan.”
