Brandie Sicca, Humanities
Brandie has over 16 years of experience in the field of education, and she is deeply motivated by her own experiences as a neurodivergent individual. She received her undergraduate degrees from Monmouth University and holds her masters in special education from Concordia University. She is currently pursuing her Ed.D in Curriculum and Instruction.
Her personal journey has inspired her to create an education system that recognizes and supports the unique needs of each learner.
Throughout her distinguished career, Brandie has accumulated valuable expertise by spending more than a decade as a classroom teacher, followed by an additional five years in educational administration.
Brandie ensures that every student receives the high-quality education they deserve in an environment where they can truly flourish. She fosters a culture of inclusivity and creativity, where students are encouraged to grow academically, socially, and emotionally. Her philosophy is embodied in her two well-known taglines: “make smart choices, and have a dance party”—a reminder to approach challenges with joy and creativity, and “break barriers and build futures”—which reflects her dedication to creating opportunities and possibilities for every student, regardless of their individual needs.
Beyond her work, Brandie is a thought leader in the education community. She is constantly advocating for systemic changes that will make education more equitable and responsive to the needs of all learners, with a special focus on those who are neurodivergent. Her energy, passion, and commitment to education make her a driving force in the movement toward a more inclusive, diverse, and supportive educational landscape.
Whether through her consulting work, speaking engagements, or leadership within her organization, Brandie is making a lasting impact on education, one student at a time.
