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. Our clinicians follow your child's lead and incorporate learning opportunities into their play. By using naturally occurring opportunities for skill development, clinicians are able to facilitate skill development in an enjoyable way!

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.
