ABAcus Behavioral Health Services operates as Autism Support in San Diego from 4204A Adams Avenue in Kensington, delivering Applied Behavior Analysis therapy to children with autism spectrum disorder and developmental delays. The practice is housed within the OAS Center — a multi-disciplinary pediatric facility in San Diego's 92116 ZIP that also includes Specialized Therapy Services for speech, occupational, and physical therapy alongside Schloyer Audiology. ABAcus uses a natural, developmental framework that positions parents as active partners in intervention, building treatment goals around modeling, play, and real-world interaction rather than isolated clinical drills. The pediatric dental needs that frequently accompany sensory-processing profiles in children with ASD connect ABAcus families to the specialized pediatric care at Kensington Pediatric Dentistry and Orthodontics on Adams Avenue, where clinicians are trained to work with neurodivergent patients. Founder Beth Calarco has served on The BRIDGE Collaborative for over a decade — a transdisciplinary group of community providers, parents, funding-agency representatives, and researchers developing care plans for children with disorders of relating and communicating from the earliest stages. Adams Avenue through Kensington anchors a concentration of pediatric support services, and the 4204A block places ABAcus within walking distance of the Kensington-Normal Heights Branch Library. Developmental milestones established through ABA sessions at ABAcus feed directly into the classroom-readiness skills that early-education programs build at Grace Kids Preschool, where structured play and social-skill development continue the behavioral progress initiated in therapy. ABAcus offers both in-center and in-home ABA services, with a comprehensive track for children ages two through four designed to prepare them for mainstream classroom integration and a focused-care track for school-aged children addressing after-school behavioral goals.
