Vyju
Founder
Vyju Kadambi is the Founder of Southwest Montessori Academy. Her journey began as a parent, witnessing the remarkable growth of her daughter during her early years in school. Inspired by the Montessori approach, Vyju enrolled in a teacher training program, which eventually led her to the unexpected role of director at a Montessori school. This experience became a turning point in her life, guiding her towards the founding of Southwest Montessori Academy (SMA).
Recognizing the need for a Montessori school in the southwest region of Fort Wayne, Vyju, with the support of her husband, established SMA in 2013. Through seven years of dedicated efforts, the school flourished under her guidance, reaching its full capacity and fostering a committed board and staff who could continue the school’s mission even without her as Head of School. Vyju continues her work at SMA as a board member.
In 2021, Vyju’s passion for Montessori education for all children guided her into working for Montessori Public Policy Initiative. The organization is focused removing policy barriers to the full implementation of Montessori and increasing access of Montessori education to all families regardless of economic abilities.
Vyju Kadambi’s unwavering commitment to Montessori education and her tireless efforts in establishing and nurturing Southwest Montessori Academy have made her a respected figure in the field. Her journey continues to shape the lives of children and advocate for the principles of the Montessori philosophy.
