How It All Started

Spectrum of Hope was founded by a mother who felt lost after her son was diagnosed with autism spectrum disorder. After learning about the disorder, Casey did everything she could to help her son and fell in love with ABA therapy. She strives to continue to learn, to grow, and to help others in the community to access effective, evidence-based treatment. 

She has been in the field of ABA since 2010. She graduated from Kaplan University in 2012 with a bachelor's degree in Early Childhood Education, graduated from Kaplan University in 2014 with a master's degree in Applied Behavior Analysis, and became a Board Certified Behavior Analyst in 2015. 

She specializes in early intervention, parent training, IEP development and consultation, verbal behavior, pivotal response training, behavior reduction, social skills training, self-help and independent living skills, natural environment teaching and discrete trial teaching. Spectrum of Hope serves individuals from the age of 18 months to 18 years old and is in-network with Tricare, Blue Cross Blue Shield, and Georgia Medicaid.
