Exceptional Therapy for Exceptional Children

autism school orlandoautism treatment

Applied Behavior Center for Autism was founded in April 2004 by Hyndi Khomutetsky, MS, BCBA and Bobbi Barber, MS, BCBA. They both have backgrounds in the public school system, in-home private therapy, out-patient treatment centers and residential facilities.

All therapists at Applied Behavior Center for Autism are Registered Behavior TechniciansTM (RBTTM), which is a paraprofessional who practices under the close, ongoing supervision of a BCBA, BCaBA, or FL-CBA. The RBT is primarily responsible for the direct implementation of behavior-analytic services. The RBT does not design intervention or assessment plans. It is the responsibility of the RBT supervisor to determine which tasks an RBT may perform as a function of his or her training, experience, and competence. The BACB certificate supervising the RBT is responsible for the work performed by the RBT on the cases they are overseeing.

To be qualified as an RBT, therapists must be 18 years of age, possess a minimum of a high school diploma or national equivalent, complete 40-hours of training, complete a criminal background check, pass the RBT Competency Assessment, and pass the RBT examination. To learn more about RBT qualifications, please visit the BACB website: http://bacb.com/wp-content/uploads/2015/08/150819-RBT-competency-assessment.pdf.

Anja Cope, BS


Administrative and Clinical Assistant Winter Garden Campus
I became an RBT in a sort of roundabout way. I started college as a theatre major, but ended with a Bachelors of Arts in Sociology and Anthropology. In December 2014, I left my bank job to pursue a career that I felt was more rewarding. I looked at behavior analysis as a gateway to becoming a classroom teacher, but fell in love with the kids I worked with. Helping them improve their lives improved mine. Recently, my husband, my son, and I relocated to the Orlando area from southeast Georgia. I thought I wanted to stay home, but the call of ABA got me again and I joined ABC in October, 2015.
