During her formative years, Puan Sri Kai Yong Yeoh was an outstanding student both academically and in the performing arts. She would go on to make outstanding contributions in her teaching career, educating students in Mathematics. More importantly, she helped realise their full academic potential in the subject, regardless of their learning abilities.

In spite of full-time teaching engagements, she personally saw to the needs of her own children, tutoring and nurturing them to be well-rounded individuals rooted in strong family values. Although she has since retired from the teaching profession, she continues her passion by tutoring her grandchildren in Mathematics.

Since then, she has also sat on the Jalan Davidson Primary School Board of Governors where she taught for years and founded the school band. She holds the position of General Advisor to the Parents Teachers Association, the Alumni Association and the Board of Governors of the school, working tirelessly over the last 30 years to improve facilities and raise the teaching standards of the school. Outside educational causes, she generously supports other charitable projects.
