What is ABA?

ABA is the only treatment proven to improve social, language, and verbal behavior of those diagnosed with ASD.  ABA therapy incorporates play based learning with individualized treatment plan goals.  Each child works 1-to-1 with a Registered Behavior Technician or Behavioral Therapist while at the clinic. Each client will receive between 20-40 hours of clinic based therapy per week.  A Board Certified Behavior Analyst (BCBA) oversees treatment and treatment plan goals for each client.  A meeting to discuss progress, provide training, and model strategies utilized will be scheduled monthly with caregivers. See the client intake tab for what is required before beginning services for your child! 

Our Mission

We strive to provide each client with an individualized treatment plan that meets all of the client and families needs.  We are here to help you every step of the way!  Email or call to request a consult with our owner!

About Us

Sonia Hall M.S., BCBA

The Missing Piece ABA Therapy LLC is locally owned and operated.  The owner, Sonia Hall, lived in Topeka, Indiana and attended Westview Jr./Sr. High School.  She attended Purdue University earning a bachelors degree and finding her passion for ABA and children with disabilities.  After working as a Behavioral Therapist for three years, she worked to obtain a Masters degree in Applied Behavior Analysis.  After obtaining her master's degree, Sonia completed the rigorous process to become a Board Certified Behavior Analyst.  After working near Purdue University for nearly a decade, it became apparent that there were no needed ABA services for children near her home town.  This is when she decided to move closer to home town and open a clinic to provide these vital services to those in her community.
