ABA therapy
ABA therapy, or Applied Behavior Analysis therapy, is a scientific approach to understanding behavior. For early learners, especially children with autism and those with ADHD, this often involves teaching communication skills (verbal behavior) and social skill training to decrease problem behaviors. We utilize a natural environment approach in our teaching as it has been proven to aid in generalization of skills.
Parent Consultations
Parent consultations are a regular part of your child's treatment when they are receiving ABA therapy. However, there are times when intensive 1:1 ABA therapy is not necessary, and parents may need assistance in managing behaviors at home. In such cases, our parent consultations provide the support and tools needed for addressing challenging behaviors at home.
School Consultations
School consultations include teacher and staff trainings within the school environment, focusing on effective strategies for classroom behavior management. With school approval, we will provide recommendations and coaching to help your child be successful in their school setting. Our services also include in-classroom behavior therapy support to improve overall classroom management and group teacher trainings.
Severe food refusal (Picky eaters)
Severe food refusal can lead to nutritional deficits, behavior changes, and delays in language development. Difficulties during meals can also create strain on family relationships. Owner, Priscilla Deal, has extensive experience in treating severe food refusal, having worked at one of the best behavioral feeding hospitals in the nation, Kennedy Krieger. She utilizes effective ABA therapy techniques to help your child overcome these challenges.
Pre-K School Readiness
Before entering Pre-K and Kindergarten, there are essential behavioral skills your child should develop for success! These skills include learning to sit for circle time, transitioning smoothly, accepting no, sharing, following simple instructions, and being able to sit and complete table work. Our school readiness program will use the priniciples of applied behavior analysis to help get your child Pre-K or Kinder ready! During the summer, this program includes group activities with other pre-k children to enhance their group skills.
Potty Training
Potty training is a necessary life skill and critical for independent living. However, potty training can be especially difficult for children with a diagnosis. At Gomez Behavior Services, we utilize an individualized, ABA therapy-based approach to teach the essential skills required for successfully using the potty, incorporating behavior therapy techniques to support each child's unique needs.
