Autism therapy
We accept

Ad Astra is Latin for to the stars.
It’s how high our kids go.

We use strategies to help your child reach new heights by implementing evidence-based therapy that is fun, play-based, and focuses on teaching skills in the natural environment. Our approach is best for kiddos aged 0 to 7 years old.

Data-based Therapy

Our custom ABA therapy plans will include family-centered and child-centered goals to help your child effectively communicate with family and peers, reduce problem behavior, and develop play, social and self-help skills. Your care team is trained to track and analyze data to consistently assess your child's growth.

Fun & Natural Care

From day one, your care team will focus on building a strong bond between them, your child, and family. We know that building skills and fixing problem behavior is done best as a team. Home-based therapy makes this approach much more natural.

Autism therapy

Personalized home-based ABA therapy.

We match your child to a care team made up of a Board Certified Behavior Analyst (BCBA) and a Registered Behavior Technician (RBT). Your care team will assess your child’s needs & growth, create a custom plan, and provide therapy in the comfort of your own home.

How does my child grow?

With therapy in a familiar space, your child becomes more independent and gains valuable skills they can use to improve in various areas of development. Your child’s Ad Astra care team will be there to provide support each step of the way.

Autism therapy

The process.

1. Free consultation

Speak to one of our team members to see if we’re a good fit and learn more about how Ad Astra can help your child. We’ll then schedule our in-depth assessment.

2. In-depth assessment

After confirming insurance coverage, a BCBA will sit down with you and your child to review concerns, observe, and develop an in-depth custom treatment plan.

3. Therapy begins!

Our clinicians will match your child to a care team made up of a BCBA and an RBT. Therapy sessions will be conducted one-on-one by the RBT and closely supervised by the BCBA.

4. Progress tracking and data review

Your child’s RBT will take data every session so that the BCBA can monitor your child’s progress and make any changes needed to improve skills and promote continued success.

5. Re-evaluation

At the six-month mark, we’ll do another in-depth assessment to make sure you and your child are happy with the progress. We’ll then set our goals for the next six months of treatment.
