Grow Your Impact. Advance Your Career.

AB Spectrum isn’t just another ABA clinic, we’re a Top Workplace recognized by the St. Louis Post-Dispatch. We’ve earned this recognition, which is based entirely on employee feedback, because we foster a culture where people feel valued, supported, and inspired to grow.

If you’re an experienced RBT ready to take the next step in your career, this is your opportunity to move beyond direct therapy and become a mentor, and role model, while still doing the meaningful hands‑on work you love.

We are proud to be the only provider of ReggioABA™ in the region, and we are growing quickly.

We are hiring Senior RBTs to help lead that growth.
