BehaviorSpan was founded by J.J. Tomash, BCBA-D in Denver in 2015. Starting as a small company that provided ABA therapy to just a few clients, BehaviorSpan has grown to an S-Corp that has Early Intervention ABA centers serving Denver and Aurora.

As our company has grown, our goal has stayed the same: to provide the most effective Applied Behavior Analysis (ABA) for children on the ASD spectrum possible. Our centers are joyful, fun, respectful, caring, and playful environments. We have carefully created environments to capture developmental opportunities for children to learn and grow, ensuring that the skills they learn help them in all environments of their life: current and future. This is the foundation that allows us to provide highly effective ABA therapy- which can most efficiently address the needs of children with autism.

The most important tool we have is our team. We love what we do. We respect and care for our clients, their families, and each other. We find joy in every accomplishment as we work and play alongside your child.
Along the same lines, BehaviorSpan is made up of a diverse group of individuals from different countries, races, beliefs, and faiths. We embrace our diversity, and it makes us strong. We will never discriminate against any individual based on their race, religion, sexual orientation, nationality, gender, sex, or beliefs.
