  • Sibonelo Hlalaphi

    Program Manager

    Sibonelo fell in love with mathematics in her grade 9 classroom, where she had heated debates with her father who was also her maths teacher. It was after this experience that she felt that every student should love and not fear mathematics. During her final year at university, Sibonelo started tutoring grade 12 students in Mathematics and Physics, and this is when she fell in love with working with young people. When not in the office, Sibonelo is probably climbing a mountain or having a long walk along the beach. She also enjoys arts and craft and is always starting craft projects.
