Lindsay has been working with children and adults diagnosed with a variety of neurological and developmental disabilities for 20+ years. Lindsay learned at a young age that the unique needs of special populations would determine her future path. In 1999, Lindsay began her studies at Eastern Illinois University where she graduated with a Bachelor's Degree in Therapeutic Recreation. After practicing for many years as a CTRS (Certified Therapeutic Recreation Specialist) in various settings, including outdoor recreation, home-based services, and clinical settings, she was introduced and impressed by the effective practices of ABA. It was an easy decision to return to school to continue learning the most efficient ways to provide treatment to those diagnosed with autism and other developmental disabilities. After graduating from The Chicago School of Professional Psychology with a Master's Degree in Applied Behavior Analysis, Lindsay quickly incorporated Dynamic Behavior Consulting, LTD to immediately apply her newly acquired skills, knowledge, and abilities to serve individuals diagnosed with autism spectrum disorders. After several years of private practice Lindsay met and teamed up with fellow BCBA, Stephanie Beaulieu, with the goal of servicing a larger population. Following successful experiences contracting with large agencies, school districts, and hospital groups, Lindsay and Stephanie founded Academy of Excellence in Learning, Inc. and Center for Behavior Intervention, Inc. in 2012. Lindsay continues to passionately dedicate all her efforts to address the needs of individuals and families in multiple environments with respect and dignity, ensuring the unique needs of all learners are met with the most researched and effective treatments and educational methods.


Stephanie has been working with children and adults diagnosed with neurological and development disabilities for over 15 years. Growing up, Stephanie knew she wanted to work in a field that served children and adults in need of supports, but was not sure of the best direction for her education until she began working with children diagnosed with developmental and physical disabilities. Once she began working in the field of developmental disabilities, Stephanie knew she had found her passion. After graduating from Kansas State University with a Bachelor's Degree in Psychology, she was determined to educate herself in a way that would provide the very best treatment and services for the individuals she would serve. The search began, and in the fall of 2005, Stephanie began her coursework at The Chicago School of Professional Psychology for her Master's Degree in Clinical Psychology, specializing in Applied Behavior Analysis. The application of applied behavior analysis is currently the most effective treatment for children and adults with development and neurological disabilities. Stephanie knew that through the study and application of the science of ABA, she could change the lives of others by committing herself to the field and the clients she served. Stephanie graduated from The Chicago School in June of 2007 and opened her own private practice, SandyToes, LLC shortly after. She then teamed up with fellow BCBA, Lindsay Rice, and they founded Academy of Excellence in Learning, Inc. and Center for Behavior Intervention, Inc. in 2012. Stephanie's passion for teaching the population she serves is truly apparent in her work and in the change brought to the children and adults she serves.
