Dailyn Marcuello, BCBA
Clinical Director
"I have spent over 10 years in this field, beginning as an RBT and growing step by step into the BCBA role, and those experiences shape how I lead and support both children and staff. Starting on the floor gave me a real understanding of how sessions unfold, how staff think in challenging moments, and how small details impact a child’s day, which directly informs how I train and guide my team. My focus remains on meaningful progress through ABA principles and techniques, with plans built to support real life skills and independence. Our work is steady, intentional, and rooted in continuous growth, supported by a proven record of progress. Above all, children receive care grounded in knowledge and respect, and families experience consistency they can trust." - Dailyn M.
🌟 Parent Reflections
🌼 Grateful Parents
I used to feel lost. My son would get overwhelmed just walking into a classroom. No one seemed to understand what he needed. Then we found Dailyn at Sunny Day Behavioral. They didn’t just give us therapy, they gave us hope. For the first time, someone saw my son for who he is, not what he struggles with. Now he learned to greets his teacher with a smile and even plays with kids at the Doral park. I’m so grateful for the support, kindness, and consistency this team brings. I truly believe they changed the direction of our lives.

"My son used to be real scared of the bathroom crying, holding it all day. Every day felt like a fight. Miss Dailyn came and said she’d seen it before, knew what to do. And she did. She took her time, was gentle. Now he goes on his own, no fear, no fight. I thank God for her."
