Meet Our Staff

Anais Rosin is a Board Certified Behavior Analyst (BCBA) and proud graduate of the University of Kansas, where she earned her Master of Arts degree in Applied Behavior Science. Throughout her career, she has worked with a wide variety of populations — spanning children, adolescents, and adults across diverse ages, diagnoses, and abilities.

Her clinical background includes inpatient and outpatient hospital settings, in-home therapy, school environments, and pediatric outpatient clinics. She has extensive experience addressing a broad range of challenging behaviors and behavior topographies, including self-injurious behavior, aggression, property destruction, elopement, and skill deficits across communication, daily living, and social domains.

Anais founded Raven Behavior Analysis out of a belief that every person deserves individualized, compassionate support — and that families deserve a true partner in the process. She is bilingual in English and Spanish, allowing her to serve a wider community across the greater Chicagoland area.

Brett is committed to building a professional, well-supported practice that families and staff can count on for years to come.
