Mallory DeMarco
Special Education Teacher, BCBA, LBA
I have been working alongside neurodivergent individuals and their families since 2007, when a summer job substituting in a preschool classroom for children on the autism spectrum unexpectedly changed the course of my life. Although I had always planned to pursue elementary education, that experience sparked a deep passion that has guided my career ever since. From there, I worked as a respite provider in Rhode Island while completing my undergraduate degree in psychology, gaining firsthand experience supporting children and families in their natural environments.
After graduating, I continued my work in both ABA and DIR-based classrooms as a paraprofessional and substitute teacher while earning my Master’s degree in Elementary and Special Education. I spent over five years as a high school special education teacher, supporting students through critical transitional years, before beginning my journey toward becoming a Board Certified Behavior Analyst. I earned my BCBA credential in 2020 and went on to complete Level One DIR® training through Profectum, as well as a Certificate in Developmental Models of Autism Intervention from Montclair State University.
My approach is shaped not only by my education, but by nearly two decades of hands-on experience working directly with neurodivergent individuals across the lifespan. I believe deeply in a holistic, child-first model that honors each individual’s unique strengths, needs, and developmental path. True, lasting progress happens when we collaborate with a child’s entire village—families, caregivers, educators, and community supports. My long-term vision is to expand opportunities for adults over 21, empowering them to actively engage in their communities, build meaningful independence, and live full, connected lives.

Isabella Vassallo
BCBA, LBA
Hi! My name is Isabella. I’ve been a BCBA for about two and a half years, and I really enjoy the work I do. I earned my master’s degree at the University of Arizona, which was such a great experience and helped shape the career I’m in today. When I’m not working, I love spending time with my family and friends—they’re such an important part of my life. I also really enjoy cooking and baking, whether it’s trying out new recipes or making favorites to share with the people I care about. Finding a balance between work, family, and hobbies has been really meaningful to me, and I’m always excited to keep growing both personally and professionally!
