Our Founders

Through collectively over 30 years of understanding and insight, the founders of Somewhere Over the Spectrum defy the traditional ABA paradigm and have a steadfast belief in an individualized, holistic and naturalistic model of ABA, suited to not only your child’s needs, but your needs as a family overall.  

The founders have the experience to set a course for Somewhere Over the Spectrum with their dynamic, flexible and evolutionary  approach to creating a visionary unique center for Autism, to partner and walk alongside each family on their journey.
