Our Team

Phillips ABA Therapy specializes in providing ABA treatment for children with developmental delays and Autism Spectrum Disorder. We employ research-based behavior interventions combined with a personalized approach to achieve authentic, tangible results.

What We Do

We provide ABA therapy in the home, school, or community setting. We also offer Center-based services for more intensive ABA therapy needs.

We provide ABA services to decrease interfering behaviors and teach critical skills to improve socially significant behaviors. As a result, we can help increase a child's independence, self-worth, and happiness.

Parent training is provided in order to equip caregivers with essential skills to maintain your child's positive behaviors in different settings and with other people.
