Clinic video
Watch a short look inside AB Spectrum and see how our Reggio ABA approach supports child led learning, communication, connection, creativity, and development for families throughout St. Peters and St. Charles County.
Our approach
Child-led Reggio ABA blends evidence-based ABA with the Reggio Emilia philosophy, supervised by Board Certified Behavior Analysts.
Children don’t just participate—they lead. Our model integrates ABA with the Reggio Emilia approach to give children agency through painting, building, storytelling, and other expressive languages.
Reggio ABA merges scientific rigor with creativity. Every goal is rooted in ABA principles and delivered in a way that honors each child’s curiosity, strengths, and developmental rhythm.
We document progress through real-time data collection and make learning visible—tracking behavior, communication, social skills, and academic readiness.
You’re part of the team. Families participate in planning, progress reviews, and home strategies to ensure continuity and empowerment beyond the clinic.
Each child has a personalized learning path that supports behavior goals, builds confidence, and promotes lasting developmental gains.
Why AB Spectrum
Families throughout St. Charles County choose AB Spectrum because of our collaborative approach, experienced clinical team, and child centered Reggio ABA environment designed specifically for young children with autism.
