ABA Therapy Programs

Clinic Based Program

Ages: 1-7 Years Old

Up to 40 hours of ABA therapy weekly can be provided, per medical necessity.

Autism and Behavioral Spectrum is proud to offer large Therapy Facilities. Research has shown that children need room to explore and flourish. Our facilities are much larger than your typical ABA therapy clinic allowing your child to really enjoy their time at our center rather than feeling as if it is a doctor/therapy visit.  


AB Spectrum offers 1 on 1 Early Intervention ABA and Speech Therapy in a typical "Preschool" environment. We create ABA therapy goals into all our activities which include pet visits, music therapist, community outings, and bunch of NET (Natural Environment Teaching) activities all while incorporating our ReggioABA pedagogy. Now children with Autism will have the opportunity to learn and grow in a natural environment that embraces their skills and encourages individuality.


We have seen great success as many kids have graduated our program joining their typically developing peers in school.

In-Home Program

Ages: 1-12 Years Old

Up to 25 hours of ABA therapy weekly can be provided, per medical necessity.

ABS offers a comprehensive treatment program centered on what our clients need most, and that includes providing therapy in their own home. In-home therapy offers the opportunities to explore and learn through the ReggioABA way in your own backyard, playroom, or even through trips to the local park.


Your BCBA and RBT will work hand-in-hand to support and show you how to work on programs within the daily routine of your child’s natural environment.


Ages: 1-12 Years Old

Up to 40 hours of ABA therapy weekly can be provided, per medical necessity.

In order to maximize flexibility and opportunities for learning, ABS can provide a split ReggioABA therapy program which includes Clinic Based and In-Home ABA therapy. This option offers your child the opportunity to work on skills appropriate for a group setting such as attending to stories, social skills with peers and transitioning within a classroom environment.


Focus of this program is to give your child opportunities to work on adaptive skills such as dressing, eating, and play In-Home while also getting that daily structured therapy time in Clinic.

ReggioABA Philosophy


Our belief is that no two children learn in the exact same way, therefore, each developmental program is customized according to the needs and interests of the child. Individualized plans will be created by a team of therapists, paraprofessionals, and parents. Our plans are flexible, leaving space for strategies and interventions to be frequently analyzed and adjusted according to the progress of the child. Whether your child is showing any signs of concern in their progress or not, our center can help support and advance their development. ABS will concentrate on the interests and needs of the children by providing additional attention as a way to enrich their minds and interests.

A successful Early Intervention program works to promote and develop speech, self-help skills, communication skills, feeding and school readiness skills.  These programs are led by Board Certified Behavior Analysts also known as BCBAs and implemented by Registered Behavior Technicians also known as RBTs.  Research recommends that early intervention be provided for 30-40 hours per week.

Research done starting in the late 1980’s by Ole Ivar Lovaas showed that roughly 50% of kids who received early and intense ABA (40 hours per week) were indistinguishable from their peers after several years. This meant that those kids achieved normal intellectual and educational functioning. This is compared with only 2% of kids in the non-intense ABA group, who were receiving only 10 hours per week.

Throughout the decades, other researchers replicated Lovaas’ original findings, all with similar results. They studied and measured the type and quantity of ABA the clients were receiving. Some of the research went as far as to compare groups of kids who were receiving exclusively ABA therapy, to those who were receiving an eclectic approach of Speech, OT, ABA, and special education. The ABA group significantly outperformed the eclectic group in treatment gains. In 2010 researchers reviewed the literature on early intensive ABA and determined that children receiving 35 hours per week or more had the best treatment gains when compared to those receiving less.
