​Guiding Principles

At The Missing Piece ABA Therapy, LLC, our mission is to provide high-quality, compassionate ABA and autism services that support individuals and their families in achieving meaningful and lasting success. Our work is guided by the following core values:

-Honesty

We believe that trust is built through open, honest, and transparent communication. We are committed to maintaining integrity in every interaction with our clients, families, team members, and community partners.

We strive to empower individuals and their families by teaching meaningful skills that promote independence, confidence, and self-advocacy. Through individualized and evidence-based ABA services, we help our clients reach their fullest potential and achieve greater participation in their daily lives.

-Accomplishments

Every achievement matters. We recognize that progress looks different for every individual, and we celebrate each milestone—whether large or small. What may seem like a small step to others can represent a significant accomplishment for our clients and their families.

-Respect and Dignity

We are committed to treating every individual with respect, compassion, and dignity. We honor the unique strengths, needs, preferences, and experiences of each client and family, ensuring they remain at the center of all decisions and services.

-Teamwork

Meaningful progress is achieved through collaboration. We value strong partnerships among clients, families, caregivers, therapists, educators, and other professionals. By working together, we create supportive environments that foster growth, learning, and success.

"Alone we can do so little; together we can do so much." — Helen Keller

At The Missing Piece ABA Therapy, LLC, we are dedicated to providing compassionate, ethical, and individualized services that help every client discover their strengths and achieve meaningful outcomes.

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! 

About Us

Owner:
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.
