Sumi Lonney
Master Mentor & Founder · Brain Magic Abacus
Sumi is the former director of a leading international abacus franchise — a role she held for over a decade before taking the bold step in 2020 to completely redesign the curriculum away from the rigid, homework-heavy model that was burning kids out.
What she built instead is the program she always wished existed: a hybrid system where self-paced abacus video mastery meets live, game-based sessions that children genuinely love. She has personally mentored thousands of students across India, UAE, Australia, Singapore, and Japan — and now brings the full program online for the first time.
