About

The Helm ABA is a team of clinical professionals and caregivers delivering personalized autism therapy grounded in Applied Behavior Analysis (ABA). We combine scientific precision with deep empathy to create a care model that supports families across North Texas with clarity, consistency, and compassion.

Many of us have personal connections to autism. Whether as parents, siblings, or advocates, our experiences deepen our commitment and shape the way we deliver care. We understand the emotional complexity of raising a child with autism, and we walk beside families every step of the way—with clarity, compassion, and clinical excellence.

Clinical Expertise Meets Compassionate Care

Our leadership team embodies a dual approach: clinically rigorous yet deeply compassionate. We understand that navigating autism’s complexities requires more than just theoretical knowledge—it demands a heartfelt understanding of each child’s unique needs.

That’s why we integrate focused therapy with the latest research and best practices in Applied Behavior Analysis (ABA), ensuring that every intervention is individualized and truly responsive to the child’s personal growth. By focusing on increasing communication and improving overall life skills, we help each child reach their fullest potential.

Driven by a Shared Mission

The Helm ABA was founded to empower families and schools to use cutting edge behavioral therapy rooted in the principles of behavior analysis to increase safety, independence, and quality of life for individuals with developmental disabilities and their families.

The motivation behind our work is simple yet powerful: we are here because it matters deeply to us. The drive to make a difference in the lives of children with autism is more than a professional obligation—it is a personal mission. Our leadership’s experiences as family members of individuals with autism inspire our entire team to work not only as therapists but as true allies to the families we support. We are committed to helping children and families increase quality of life, fostering independence, and building meaningful connections both at home and in the community.

Why We Do What We Do

At The Helm ABA, we believe that every child has the potential to reach their fullest capabilities. Our commitment goes beyond professional dedication—it is a calling rooted in both personal and professional experience. Through our personalized therapy programs, we aim to provide an environment where children with autism can thrive. We empower families by equipping them with the tools and support they need to continue their child’s development at home, creating a seamless, supportive journey that extends beyond our therapy sessions.

By providing focused therapy and integrating tailored services into everyday life, we ensure that each child receives the attention, care, and guidance they need to improve communication, foster social skills, and enhance overall quality of life. We celebrate every milestone and are deeply committed to helping every child and family achieve long-term success.
