How were you introduced to ABA?

"I have been working with individuals with intellectual and developmental disabilities in varying capacities since 2004. My passion for this population increased as the years progressed especially during my time in grad school studying educational psychology and bridging the gap between the IDD population and psychology. My ABA career started shortly after graduating in 2018 and haven’t looked back since!"

Alanna Paule, RBT

Office Administrator

Alanna has been on our team for over a year and is the only employee in a "hybrid" role, splitting her time between both 1:1 therapy sessions and office administrative tasks. 

How were you introduced to ABA?

I was introduced to ABA after being a paralegal with a firm that worked to advance the rights of those with disabilities. My supervising attorney worked closely with a BCBA and I was able to shadow a few ABA sessions and thought I would give it a try myself. With this, I realized I enjoyed the practice of ABA, the constant and consistent positivity, and stuck with it ever since.

A few fun facts about you:

I make music under a semi-popular pseudonym and love to create musical scores for every major event in my life.
