Services
In-Home Therapy
In-Home ABA therapy for children ages 2 to 9 years with a diagnosis of autism. By offering services in the home, it eliminates the need for additional teaching to generalize skills to the child's natural surroundings. The goal is to make learning and progress seamless in the places that matter most to your child's development.
School Setting
Support your child's academic progress with ABA therapy in an educational setting. In-school ABA therapy offers customized support to help your child succeed, while also promoting participation in whole group instruction and peer interactions. This approach facilitates their access to more inclusive environments.
Parent Coaching
Parent coaching equips caregivers with tools and strategies to manage their child's behavior outside of therapy. Collaboration with parents is essential to identify their child's needs and create a tailored plan, guiding them on reinforcing positive behaviors, managing challenges, and promoting skill generalization.
Collaboration
Active collaboration with a variety of professionals including teachers, speech therapists, occupational therapists, physicians, and all those who play a pivotal role in a child's treatment plan. By forging these connections and maintaining consistency across settings, we create an environment where all aspects of their growth are addressed.
Workshops and Group Trainings
Virtual workshops covering various ABA principles, such as the A-B-C Model, reinforcement, antecedent strategies, behavior management, and communication are offered. These workshops are informative, engaging, and practical, offering teachers and parents real-life tools and strategies.
