Frequently Ask Questions

What is ABA therapy?

Applied behavior analysis (ABA) is the science in which the principles of behavior are applied systematically to improve socially significant behavior and experimentation is used to identify the variables responsible for behavior change” (Cooper, Heron, & Heward, 2007). In simpler terms, ABA is the science of altering the environment and applying strategies to reduce challenging behaviors while increasing adaptive behaviors. We believe that each individual should be part of the planning process for their engagement in ABA therapy. ABA therapy targets social skills (in a neurodiversity affirming way), communication, daily living skills and more by applying evidence-based methods to improve a child’s ability to interact with their natural environment. We focus on the use of intrinsic motivation to work with the child while promoting a safe and controlled environment, giving them the best chance at success. Our approach is completely individualized for each child. We seek to understand the function (or the reason) behind each behavior with the knowledge that behavior is communication. We attempt to listen to this communication by implementing evidence-based interventions while keeping a neurodiversity-affirming approach in mind each step of the way.

What does the current wait list look like?

The waiting list for Advanced Behavior Analysis changes frequently depending on staff availability. To get our most current availability and wait list information, please email our billing manager at Tara@Advancedbehavioranalysis.com.

How does scheduling work?
Advanced Behavior Analysis schedules ABA sessions into 3-time blocks. Block 1 includes 8/9am-Noon, Block 2 includes Noon-3pm and Block 3 includes 3-6pm. We have adopted this scheduling system as it allows the technicians to have consistent schedules. This helps us with retention and organization. Individual scheduling needs are handled by our scheduling department.
What is the process for getting started with ABA therapy?
Once insurance authorization for beginning the assessment process has been received by our billing team, a Board Certified Behavior Analyst (BCBA) will be assigned to the case. During the first meeting, the BCBA will get to know the family, the concerns of the family, get to know the child, observe the child and use assessment tools to determine what strengths the child already possesses and what skills can be worked on to further grow the existing strengths. Each company uses different assessment tools; we use the ABLLS, Vineland III, VB-MAPP and AFLS assessments. While we may not use all assessments, the BCBA will determine which assessments are appropriate for the child based on the information given from the parent. After assessments are completed, the BCBA will create an individualized treatment plan that is reviewed by a regional manager to ensure the plan follows neurodiversity affirming practice in line with our values. Once the treatment plan is approved by the parent, the treatment plan will be submitted to insurance for approval. After approval, a team will be created and assigned and services can begin.

Andrea Bruerton

My son Collin (4) was paired up with an AMAZING team. Our BCBA is Jillian and our RBT is Camille. Collin calls them his Jillie and Milk. They have truly been amazing. When we started this journey Collin maybe said 10 words functionally. He is now talking in 3 to 4 word sentences. He can identify emotions in others and is learning how to express his wants, needs, and feelings. He is learning how to play with others and so, so much more. They disguise everything as fun games or activities. Even my 2 older daughters want to join in. Collin received a diagnosis of ASD when he was 2yr old. Our Pediatrician really stressed the importance of ABA therapy. To be honest I was very reluctant as I have heard mixed reviews. After calling about 10 different companies to get information about their programs I found ABA. I was looking for someone that would work with me on how many hours a week he would be required to do. Most places I talked with wanted a minimum of 20 hours a week. At 3yrs old that is to much in my opinion. I also wanted in home and clinic sessions. I want to be involved. They have been willing to work with me on all of the above and so much more. Jillian and Camille are phenomenal at what they do. They truly care and love my little boy. I could not ask for a better team. He looks forward to going to the Clinic (Milks House) and them coming to our home. I can honestly say that I whole heartily trust them and feel so lucky that they are in our lives.
