Thank you for taking the time to research, explore, and understand our operating philosophy and guiding principles.

Our goal is to assist parents and caregivers to find the very best Applied Behavior Analysis (ABA) services that fit the needs and resources of each family.

While we understand and appreciate that all too often families are left with the “we will take whatever we can get” approach, it is still essential to know how your provider operates, especially when you give them time and access to your child.

We know how important it is for families to get the services that they need but we also believe that bad ABA can be worse than no ABA. Families need to make informed decisions about what works best for them – even if it is not with Sadowsky Autism Services.

We realize that there is a lot of content on these pages. We are putting as much information as possible on the site because our experience tells us that most parents will read every word as they work to produce the best outcomes for their children. We want to be as helpful as possible in that decision-making process and are providing as much information up front as possible.

Letter to Parents

Welcome Families!

Thank you for choosing Sadowsky Autism Services as your service provider.

I realize that the process of initiating services for your child with autism can be challenging and frustrating. My goal is to make the process as easy as possible by working directly with you throughout the entire process.

I created Sadowsky Autism Services because, having worked with hundreds of families, I know the remarkable impact Applied Behavior Analysis (ABA) can have in the lives of children with autism. However, providing services for families of children with autism is more than providing a curriculum, assessments and behavior plans. I understand the importance of truly individualized ABA programs. My mission is to provide ABA services that meet the specific needs of each family and that reflect the unique personality of each child.

Please feel free to contact me at with any questions about my philosophy, our mission at SAS or our ABA services.

I look forward to working with you.

Our Impact

We believe that our philosophy and approach to providing ABA to our clients is both effective and unique.

In order to maintain and expand our approach, we actively support the professional development of all of our staff members. We are proud to support the progression of our Registered Behavior Technicians (RBT) as they become Board Certified Behavior Analysts (BCBA). To date, eight of our BCBAs started their careers with us as RBTs – and there are more on the way.

During the height of the COVID-19 pandemic in 2020, we closed our doors for eight weeks while we hunkered down to let the big COVID wave sweep through our service areas.  

We continued to pay all of our staff while we were closed and are happy to say that we were able to retain every single one of our employees as we slowly returned to a more normal life.  The countless years of collective experience that we were able to retain contributes greatly to the success of our program today.

During the summer of 2022 we completed the installation of artificial turf in our two outdoor play areas.

We now have all-weather access to our outdoor play structure as well as our covered water play area. Playing in the sprinkler, painting on the walls, or enjoying some time in the cooling mist is all possible due to our new turf!

Our parents and caregivers are closely involved in the therapeutic process.

They have access to review data, work directly with their BCBA and RBT staff, participate in parent specific training in their own homes, and are able to observe and participate in all of our programs (whether at home or at our center) so that we can ensure a consistency of effort. It does not help if the interventions are only successful at our center with our staff members – the programs need to be just as effective for our families when they are at home in their natural environment.
