Sum of Learning

UPDATED: September 10, 2018

Sum of Learning offers behavioral and educational services to families and children, aged 2 to 18 years, affected by autism and other related developmental disorders.

Our commitment to children: Every child, with or without disability, can learn and has the right to effective education. Our teaching approach emphasizes on understanding every child has unique learning needs and characteristics, and therefore, teaching should not be a one size fits all approach but rather, requires individualization. We believe that learner’s failure is instructor’s failure, and a good teacher will constantly improve and modify instruction to meet the unique needs of the learner.

Our commitment to families: Family involvement in every child’s learning is critical. We are committed to developing a trusting, respectful, and collaborative working relationship with each family we serve. Our goal is to advocate for your child together through partnership.

Our commitment to the Autism and ABA community: We partner with school districts and local communities to provide training workshops; we are sponsors for various non-profit organizations who serve children and families with special needs; and we participate in community services that support underserved families to access services. Our ultimate goal is to increase public knowledge of ABA and improve quality of ABA services in our community.



Children with autism spectrum disorder (ASD) present unique learning needs and require highly specialized and individualized treatment. Behavioral treatment based on the science of applied behavior analysis (ABA) has garnered the most empirical validation and is considered the standard of care for the treatment of ASD. Sum of Learning provides treatment that is evidence-based, and is guided and supported by empirical data. Our clinical team includes both doctoral and master level board certified behavior analysts, and ABA therapists, who are trained rigorously in the application of ABA.
Many learners with ASD require high numbers of learning opportunities to acquire new skills. Increasing teaching efficiency is as equally important as providing effective intervention in order to teach the most information effectively in the shortest amount of time and with the least teaching opportunities. Our Founder and Executive Director, Dr. Chung, has conducted research to investigate and identify efficient teaching strategies for children with ASD. She is proud to share her research and clinical experiences to her team through ongoing professional development.


Learning does not have to be stressful. Children learn best through play. Our clinical staff are engaging, and they sure know how to create and embed valuable teaching opportunities in fun, enjoyable, and developmentally appropriate play activities.


Children with ASD are children first. We embrace their differences, abilities, and uniqueness. We support their needs and celebrate their success, regardless of intellect or background. We believe all children, with or without disabilities, have the capacity to learn, grow, and succeed. Our team strives to assist each child in achieving measurable and positive outcomes in all areas of life.
Family involvement plays an integral part of every child’s learning experience. We value every parent’s input and work collaboratively with each family to develop an individualized treatment plan that will tailor the unique needs of both the child and the family. Sum of Learning recognizes and embraces the differences each family brings to us. We are proud to serve families from diverse cultural and linguistic backgrounds, and we strive to improve the quality of life for you, your child, and your family.
