What started as a small idea in Jacksonville has grown into a trusted ABA therapy provider serving families across South Florida. We are committed to helping individuals with autism and developmental disabilities gain independence and thrive.
South Florida Behavior was founded with one goal in mind: to provide compassionate, high-quality support for individuals with autism and developmental disabilities. What began in 2007 as a small respite and recreational service under the name Peace of Mind Jax in Jacksonville, Florida, has since grown into a leading ABA therapy and educational provider in South Florida.
Our journey is deeply personal. Founder Michelle Castaños, BCBA, was inspired by her cousin, Miguel, who was diagnosed with ASD in 1997. Growing up alongside him, Michelle saw firsthand the challenges families face—from limited access to quality therapy to the need for ongoing support beyond childhood. These experiences shaped South Florida Behavior’s commitment to providing individualized ABA services that evolve with each person’s needs.
In 2017, we relocated from Jacksonville to Miami, expanding our reach to better serve families. Today, South Florida Behavior operates two centers—one in Doral and our newest location in Weston, which opened in March 2024. Our team of over 50 dedicated professionals now serves more than 75 families across Miami-Dade and Broward counties, providing individualized ABA therapy, educational support, and parent training to help every individual thrive.
South Florida Behavior isn’t just a therapy provider—it’s a family. Our guiding principle is simple: Would this service be good enough for Miguel? If not, we don’t offer it. Miguel, diagnosed with ASD in 1997, has been the driving force behind our services. Every program we develop is designed to ensure real, meaningful progress—just like the support we envisioned for him.
Today, Miguel remains the heart and inspiration of South Florida Behavior. He even designed our logo, branding, and colors! You’ll often find him at our centers, helping out and connecting with families.
To enhance the quality of life for the individuals we serve through compassionate, individualized ABA and educational services, while promoting inclusivity and fostering meaningful collaboration with families and the community.
We approach every individual and family with kindness, empathy, and understanding. We recognize that every journey is unique, and we provide personalized, supportive care to help children and adults succeed.
We believe in working together—with families, caregivers, educators, and other professionals—to create the best possible outcomes. Success is built on teamwork, communication, and shared goals.
We hold ourselves to the highest standards of quality and ethics in ABA therapy. Through ongoing training, research-based practices, and continuous improvement, we ensure that our clients receive the best possible care.
Our goal is to help individuals build independence, confidence, and autonomy in their daily lives. We empower our clients, families, and team members to grow, learn, and reach their full potential.
We are more than a company—we are a family. We foster a supportive and inclusive environment where everyone feels valued, respected, and connected. Our impact extends beyond therapy sessions to uplifting the communities we serve.
We celebrate diversity and ensure that every individual—regardless of background, ability, or identity—feels welcome and supported. We strive to create a safe, equitable, and culturally responsive environment for all.
Michelle Castaños, BCBA, founded South Florida Behavior with a dream of helping families like her own. Inspired by her cousin Miguel, who was diagnosed with autism in 1997, Michelle saw firsthand the challenges families faced in finding quality support. As a 19-year-old college student, she started Peace of Mind Jax, a small respite and recreational company dedicated to providing care for children with autism. What began as a passion project soon grew into something much greater—evolving into South Florida Behavior, an ABA agency committed to empowering individuals with autism and developmental disabilities.
Driven by her love for Miguel and her passion for helping others, Michelle has dedicated her career to ensuring that every child and family receives the support, guidance, and compassion they deserve. She continues to lead South Florida Behavior with the same heart and commitment that started it all.
