Senior Behavior Analyst
Julie Pantaleon, MA BCBA
Senior Behavior Analyst
Julie grew up wanting to teach and work with children. And in many ways, her work in the field of ABA reminds her of a therapeutic teacher. She received her B.A. degree in Psychology from UC Davis and began working as an early intervention specialist. She thoroughly enjoyed working with children during their toddler years; and after 3 years, returned to school with the intent to continue to expand her skills and grow as a therapist.
Julie received her M.A. degree in Clinical Psychology from Argosy University, with an emphasis in family therapy. Her practicum and internship placements honed her perspective to view clients as part of larger familial and cultural systems. For close to a decade, Julie has found that children and adolescents progress well when parents, caregivers, siblings, peers, teachers, and community service providers are included in their treatment plans. In addition, she tends to approach her work with her kiddos with an attachment-based emphasis, working to build a trusting and predictable relationship with the family system that she’s entering into.
As an adolescent, when Julie’s family emigrated to the U.S., she became acutely aware of the challenges that come with communicating with others when there are language barriers and cultural differences. Both her personal experiences and professional training helped to develop her desire to teach children, support their families, and continually learn from others. She diligently strives to support children in acquiring crucial communicative and coping skills needed for them to express their needs and share their joys. “It is my hope to be a part of their journey, as they learn, to the best of their abilities, how to adapt and navigate our diverse neuro-typical worlds.”
