About Us

We help people understand themselves and how they relate to others.

We break down topics like stress, communication, and regulation so they feel clear, useful, and human. When people understand their nervous system, they can make more grounded choices — about how they live, work, and connect. Our tools are science-based, experience-tested, and made for real life.

Who We Work With

We support:

  • Professionals and teams under pressure

  • Founders, facilitators, and care providers

  • People looking for science-based tools that actually help

  • Organizations building nervous system-aware cultures

Whether you’re navigating burnout, holding a lot for others, or just want to feel more steady—we’re here to help.

Why Expanding Circles

We believe that when people feel more regulated and resourced, it changes how they show up—for themselves, their teams, and their communities.

That’s how care spreads: person by person. Circle by circle.

We’re a psychologist and a movement scientist who teamed up to make care more practical, accessible, and human.
