SERVICES AT
ALLY BEHAVIOR
At Ally Behavior Centers in Fairfax, Virginia, we support your child through a multidisciplinary, person-centered approach to care. Our team of specialists includes speech-language pathologists, occupational therapists, developmental pediatricians, psychologists, and board-certified behavior analysts (BCBAs) – all working together under one roof to provide expert ABA therapy and related services.
These professionals collaborate daily, consulting with each other to develop a program tailored to your child’s unique needs and goals. For instance, if your child struggles with mealtimes and eating, their “SOS Feeding certified” occupational therapist may train other team members on strategies that can be incorporated into their daily ABA therapy program. This approach ensures focused, personalized care while reducing stress for your family by removing the need to find additional services outside of ABA therapy.
How does ABA therapy work at the Fairfax location?
Our ABA therapy uses a step-by-step, play-based approach with positive reinforcement, tailored to your child’s unique needs. Children build real-life skills like communication, social interaction, daily routines, and independence — all in a supportive, center-based environment at our Fairfax location.

Is Speech & Occupational Therapy important for my child?

WHAT MAKES
ALLY DIFFERENT?
At Ally Behavior Centers, we provide the gold standard in autism treatment - full-time, multidisciplinary, center-based ABA therapy designed to help children develop essential skills for lifelong success.
Is center-based ABA therapy better than home-based therapy?
Yes — research consistently shows that center-based ABA therapy produces stronger gains in social and communication skills for early learners than home-based models. A structured center environment allows children to practice skills with peers, generalize behavior across settings, and access multiple therapists and specialists in one place. Ally Behavior's Fairfax center is designed specifically around this model.
Our structured, center-based model creates an ideal learning environment, allowing children to:
- Build skills that generalize in real-world settings
- Receive multiple forms of therapy under one roof
- Transition smoothly to general education settings such as Kindergarten
