Heather Bania, BSc, discovered her passion for applied behavior analysis (ABA) while obtaining her bachelor’s degree in human development from the University of Wisconsin-Green Bay. She started her career with the Green Bay Learning Center as a behavior technician (BT) in 2001.

Later that year, she transferred to the Milwaukee region, where her career continued to flourish. She was promoted to managing technician, then clinical supervisor, and ultimately, to clinical director.

Heather is the senior regional director for the Milwaukee region, where she oversees the operation of four Learning Centers. Her journey from behavior technician to senior clinical director is a testament to her dedication and expertise in ABA.

Away from her professional commitments, Heather spends time with her husband and two children. She has an eye for decorating and savors peaceful moments relaxing by the lake.
