Unlocking The Spectrum was created with the mission of making ABA Therapy accessible to ALL children with autism by providing the highest quality ABA Therapy services to areas of need. Research, conducted over the past 60 years, has shown ABA therapy to be the most effective treatment for children with autism. In fact, ABA therapy is the only therapy endorsed by the Surgeon General as an effective treatment for autism. At Unlocking The Spectrum, we believe that an effective ABA program is an essential component in allowing children with autism to reach their maximum potential.
