Meet Rachel

A behavior analyst who believes the science of behavior change belongs in real life.

Rachel Callahan is a Board Certified Behavior Analyst, Certified Personal Trainer, and Nutrition Coach with more than 14 years of professional experience in the field of behavior analysis.

Her work has included adults with intellectual and developmental disabilities, behavioral gerontology, community-based behavior support, caregiver and provider consultation, working as a public school district behavior analyst, law enforcement training and collaboration, and health and fitness coaching. She created Built Better Behavior Consulting to offer practical, individualized services guided by meaningful outcomes rather than generic programs.

Rachel is passionate about helping Board Certified Behavior Analysts explore opportunities beyond traditional practice settings. Through education, consultation, and practical resources, she encourages BCBAs to recognize how behavior analysis can be applied across diverse populations and areas. Her goal is to help clinicians broaden their skills, build careers that align with their interests, and expand the reach of behavior analysis beyond its most familiar applications.
