At ABA Works, we use evidence-based Applied Behavior Analysis (ABA) to help children develop skills that support long-term success. Therapy programs are individualized based on each child’s strengths, needs, and developmental goals.
Our approach emphasizes:
• Individualized treatment programs and Social Skills Groups
• Evidence-based ABA strategies
• Collaboration with families and caregivers
• Support for communication, social, and daily living skills
We believe that meaningful progress happens when ABA therapy is structured, individualized, and focused on each child’s unique learning style. Click here to read more about our early intervention services.
ABA Works began with a simple but powerful realization: when children are given the right support, they can make meaningful progress in ways that change their lives and the lives of their families.
The inspiration for ABA Works comes from the experience of one of our founders, Lilyan W. J. Campbell, LMFT, BCBA.
While practicing as a clinician in Europe, Lilyan frequently worked with children who struggled with communication, emotional regulation, and behavior challenges. Many of these children were diagnosed with Autism Spectrum Disorder, ADHD, or related developmental conditions. Although she was passionate about helping them, she often felt limited by the tools available at the time and wanted to find more effective ways to reach and support these children.
In 2005, Lilyan was introduced in the USA to Applied Behavior Analysis (ABA). This experience changed the direction of her career.
While working as a Behavior Therapist, she began providing intensive therapy to a four-year-old boy who was non-verbal and frequently engaged in tantrums and aggressive behaviors. Much of his day was spent watching television, and attempts to engage him in play were often unsuccessful. Building a connection with him required patience, consistency, and the use of structured behavioral strategies.
Through daily therapy sessions with the child and close collaboration with his mother, Lilyan applied evidence-based ABA techniques. She focused on reinforcing positive behaviors, giving clear and simple instructions, and supporting the child through challenging moments while maintaining consistency.
At first, the behaviors intensified. The child’s tantrums became more frequent and more intense—a response known in ABA as an extinction burst, where behaviors temporarily escalate when they no longer produce the desired outcome. These moments were difficult for both the BT and the family, but the child’s mother remained committed to the process and trusted that the work would eventually lead to progress.
After several weeks of consistent therapy, something remarkable happened.
The child began to realize that tantrums no longer helped him avoid instructions. Slowly, he started to engage. He sat at the table to play simple games, began identifying pictures on learning cards, and gradually increased his vocalizations. Eye contact improved, waiting skills developed, and communication began to emerge.
What once seemed impossible began to unfold step by step.
Witnessing this transformation had a profound impact. It demonstrated the power of structured, individualized ABA therapy and the meaningful change it could create for children and families.
Inspired by this experience, Lilyan decided to dedicate her career to ABA and to build an organization focused on providing effective, compassionate, and individualized services. In 2014, ABA Works was founded with the goal of bringing together passionate professionals who are committed to helping individuals reach their fullest potential.
Since then, ABA Works has continued to grow while remaining grounded in its core values: dedication, collaboration, and a commitment to evidence-based care.
Aspects that continue to distinguish ABA Works are the strong emphasis on parent training and family collaboration, and our mock (pre) school. Parents are an essential part of the ABA therapy process. By learning the same strategies used during sessions, families are able to support their child’s development throughout daily routines and activities. In addition, our mock (pre) school supports children to follow a daily routine and become prepared for school.
ABA Works also values collaboration with other professionals. Our team works alongside Speech Therapists, Occupational Therapists, educators, and other providers to ensure that each child receives well-coordinated support across different environments.
Today, ABA Works continues to expand its services while staying true to the original vision: helping individuals build the skills needed to communicate, learn, and live more independently.
At the heart of ABA Works is a team of dedicated professionals who share a passion for making a meaningful difference in the lives of children and families.
