Ashley Osbun joined the Trumpet Behavioral Health Team as a Behavior Therapist/RBT in April of 2016. Prior to working with TBH, Ashley had worked as a Paraprofessional Assistant for ANOVA Education, Program Assistant for the Boys and Girls Club of America, and as a Behavior Therapist/RBT for a previous ABA service provider. It was in Ashley’s first week of ABA training at Trumpet that she knew she was meant to pursue her BCBA. During that first week, she was unbelievably inspired by the knowledge and professionalism of the Clinicians, intrigued by the complexity of the science and how beneficial ABA is for a vast amount of behaviors and skills. Ashley enrolled in a graduate program for the upcoming Fall semester and never looked back. She graduated with a M.Ed. in Applied Behavior Analysis in 2018, and became a Board Certified Behavior Analyst in 2019.

I began working with children and adults having developmental disabilities, specifically those diagnosed with Autism Spectrum Disorder, in 2008. From the moment I set foot into the classroom of the student whom I was a Behavior Therapist for, I knew that within THIS classroom is where I would remain. “This classroom” takes on many different forms: the home, the playground, the grocery store, at the kitchen sink, on the city bus, in the hearts of our families, and in the minds of our learners. “This classroom” is not just any classroom; it is a place where those who need it most are provided the opportunity to learn; to learn in the way that suits THEM and is individualized to their specific needs. My passion for my work with ASD individuals continues to grow with every single success moment that I encounter. This passion is what drives me as a practitioner of Applied Behavior Analysis (BCBA) to provide effective and meaningful behavior change programs to those that I serve, and the TEAM that helps us get there: The Behavior Therapists (RBTs) I train and mentor who implement ABA strategies with our learners, the families I support to improve their overall quality of life, and the interdisciplinary team members I collaborate with and guide to help make their services more impactful. When best practiced and best taught, consistent ABA therapy has the potential to take a “single success moment” and create multiple, significant success moments that over time, are ongoing and life-changing.
