Suzanne N. Mancil, M.Ed., BCBA

Suzi Mancil is the clinical director with over 15 years’ experience working with children from Birth to 21 years of age. She has experience teaching high school Social Studies, middle and elementary school Spanish, elementary Remedial Reading and Math, Kindergarten, and Pre-School. She has worked with students with Severe/Profound Intellectual Disabilities and Autism at the high school and elementary school levels. These students were in need of learning functional skills including: basic hygiene, washing hands, potty training, functional communication training (most were non-verbal), as well as assistance with feeding and mobility. She has also enjoyed and had the privilege to work with students with emotional and behavior disorders. Suzi became interested in Applied Behavior Analysis almost immediately after receiving her Master of Education in Special Education (with emphasis in teaching people with Intellectual Developmental Disabilities). She realized very quickly that the science of ABA could be applied to help all her students enjoy school and reach his/her full potential. She began studying ABA via Florida Institute of Technology. While studying for her BCBA, she gained experience working in-home and in clinical settings with children at varying levels of the Autism Spectrum. Applied Behavior Analysis has been incorporated into all aspects of Suzi's life. She truly believes in this science and has used it to bring about long-lasting changes that improve the quality of life for everyone she knows, including herself. Her mantra is a quote by B.F. Skinner: "...have you the courage to take up and wield the science of behavior for the good of mankind?"
