Greetings! I am Candace O’Sullivan, B.S., M.A., BCBA.

I earned my Bachelor of Science in Psychology with a specialization in Child Psychology from Central Connecticut State University in 2010, followed by a Master’s Degree in Applied Behavior Analysis and Autism from Sage Graduate School in 2013. Shortly after, I became a Board Certified Behavior Analyst (BCBA) through a rigorous national certification process.

For the past 14 years, I’ve had the privilege of supporting children, families, and educational teams across a wide range of settings. My early work with Connecticut Behavioral Health and Creative Interventions’ Birth to Three Program involved teaching foundational learning skills, supporting daily living skills, facilitating social skills groups, and coaching parents directly in their homes. These experiences helped shape my belief that meaningful progress happens when the adults around a child feel confident, supported, and equipped with practical tools.

I then joined Southington Public Schools as a district BCBA and was promoted to Lead BCBA within a year—a role I held for ten years. During that time, I conducted Functional Behavioral Assessments, developed individualized behavior plans, created behavioral programs, coached staff, and helped school teams apply data-driven strategies to support students more effectively. Working closely with both educators and families allowed me to see firsthand how much children benefit when everyone involved truly understands their needs and communicates collaboratively.

Through all these experiences, one passion stayed constant:
helping children reach their full potential by empowering the people who support them.

I created Behavioral Advocacy & Support, LLC to continue that mission—by providing parents, caregivers, and school teams with the knowledge, tools, and guidance they need to understand behavior, respond effectively, and create environments where children can thrive. Whether through school consultation, parent coaching, or individualized support, my goal is always the same: to use data, compassion, and collaboration to help children access their education, build their skills, and find success.

At the heart of my work is the belief that behavior is communication—and when we understand what a child is telling us, we unlock their ability to learn, grow, and meaningfully connect with the world around them.
