What Makes TDLC Different?

State of the Art Technology

By implementing the latest tested technology, Catalyst, into our patients therapies, we can ensure real-time monitoring of acquisition and maintenance programs and behavior reduction data. This allows for more frequent changes and updates to patient programs, while under the direct supervision of the patient’s Programmer/BCBA, which leads to more productive therapy sessions.

Comprehensive Treatment Approach

Providing ABA, Social Skills classes, Occupational Therapy and Speech Therapy, all under one roof, enables us to provide the best resources necessary to help your family. No longer will you need to drive all over Houston to receive effective treatment.

We are also able to incorporate goals from social skills classes and speech therapy into our ABA sessions, and our professional staff works together closely to make sure that each child's treatment is cohesive and consistent.

Unique Vision for Your Unique Child

We firmly believe that every child can benefit from the services we provide.

By constantly reevaluating and reassessing our modes of therapy, we are able to find the ones that best fit your child's specific needs. There is no one-size-fits-all method, and we do not believe that your child needs to change to fit into that method; we believe it is our responsibility to change our approach to fit your child's individual personality.

Our 3 Phase Program & Training

We have developed an easy-to-use and streamlined way to do data programming.

We don't want programming issues holding back your child's progress, so we are continually updating programming and materials in order to keep up with technology and research!

We offer detailed and thorough training for our staff and clients. Parents carrying over ABA/Speech techniques into the home setting is a key factor in a child's success!

TDLC Provides Help With Insurance

We know that insurance for autism can often be complex and at times, overwhelming. For that reason, we maintain an on-board staff ready to answer your questions or assist you with your insurance intake needs.
