Who We Are
At Post Oak Autism Services, we are deeply invested in nurturing family-centered, individualized autism services. Rooted in high-quality, play-based ABA therapy, we are committed to fostering growth, independence, and lasting joy within your child and your family.
Our approach celebrates every child as the unique individual they are—recognizing strengths, honoring differences, and creating space for meaningful growth. We believe in neurodiversity-affirming care that uplifts children and empowers families through compassionate autism help and behavior support.
Cultivated from a deep love for Applied Behavior Analysis, we are committed to quality, relationship-driven services that reflect our values of Joy, Family, Connection, Flexibility, and Quality.
As a family-owned practice in Round Rock, led by two Board Certified Behavior Analysts—partners in both life and practice—we are dedicated not only to your child’s progress but to your family’s well-being as a whole.
At Post Oak Autism Services, every child and family is met with the steady strength of deep roots and the encouragement to flourish and grow—at home, in the community, and throughout everyday life.
Our Roots
As a BCBA-owned and operated practice, Brooke and Drew have grown from humble beginnings, driven by a shared passion for meaningful, high-quality care.

Their broad experience gives them a unique perspective on what families truly need, services that are compassionate, individualized, and effective.
At the heart of their work, they believe in the power of connection, the necessity of quality, and the pursuit of meaningful progress. Every child deserves to feel supported and every family deserves to feel confident in their care. That commitment guides everything at Post Oak Autism Services.
