Dominika & Rebecca

Dominika and Rebecca met in graduate school in Washington, D.C.  They shared a passion for Applied Behavior Analysis and providing comprehensive services to families in the D.C. area. 


Rebecca and Dominika founded The Language and Behavior Center in 2017 with the mission of providing exceptional services to clients while also fostering a unique company culture that is supportive of employees and encourages continuous growth and development.  Focusing on living-wages, unmatched benefits, and a positive work environment resulted in the current team of highly-trained and motivated professionals that make up The Language and Behavior Center today. 


With their own families and children, Dominika and Rebecca truly understand what it means to want the best for your child and are committed to providing that to every family they work with.

Learning through Play

The Language and Behavior Center believes that a child's natural environment is the best place for them to learn.  By incorporating learning opportunities in to play, the child is less resistant to therapy and enjoys their ABA or Speech Therapy sessions. 

TLBC's evidence-based treatment is built on a foundation of parent involvement. From the start of services, parents are trained on techniques that will allow their child to flourish outside of a therapy setting.
