Passionate About Inspiring Others

Kari has many years of teaching experience, across the primary, secondary and FE sector. As a former Reading School pupil and proud parent of a Reading School student, he decided to set up his own tutoring company in 2013 to help other children achieve the benefits of a grammar school education. 

Kari came from an ordinary working class home in Reading. From an early age, he excelled both academically and in sports. From a young age, he represented the county at badminton, cricket and chess and was the captain for Reading School in both badminton and cricket throughout his time at Reading School. He always strived to achieve and it was this work ethic that led him to be held in high regard, by both his teachers and his peers. He gained a place at Bristol University in 1991. After graduating, he completed a PGCE and  become a teacher of mathematics.

He knew he possessed the qualities to be a good teacher; his students, not only achieved good results, but, quite often, they would report that they actually enjoyed his math's lessons! He was never afraid to do things differently to engage and motivate his learners. It was this ability to think "outside the box" that eventually led him to to set up his own business as a tutor. Having taught his son to pass the 11+ - with the second highest score in the county of 124.6 - Kari decided to turn his attention to the 11+ exam.

The word soon spread and the business grew  from a handful of students to a thriving, successful 11+ business it is today.

Although, he still teaches the children, his focus has recently moved to training other staff in the delivery of the course. 

Kari's main interests outside of teaching are cricket and badminton, where he still plays for local clubs.


Kari is passionate about empowering children through education. It is this passion for inspiring others and giving back that has recently led him to begin the process of opening an English Language school in India - which will hopefully become the first of many.
