I joined the ESS teaching staff in January 1966, coming on a transfer from Kenyatta College and Duke of Gloucester. I joined the Geography Department of ESS alongside Mr. J.D.Sharma and with Mr. Harry Briggs as the Principal.

Mr. A.N. Sharma (Narad) took over from Mr. Briggs. Mr. Sharma later retired to Chandigarh, India, and passed away in 2004. Mr. Frank Mendonca, who was the deputy head also retired. The headship of ESS was then taken over by Mr. Wanjohi who later joined Kenyatta College. Mr. Wanjau succeeded Mr. Wanjohi. During my tenure as a teacher and head of the geography department, I was the housemaster of the Congo house, which won the championship several times.

In 1977, I was promoted to deputy headship of ESS. In 1979, when Mr. Wanjau proceeded to the USA for further studies, I was promoted to headship. During my tenure as headmaster, we started an A' level arts class and bought the school a bus. Upon the return of Mr. Wanjau in 1981, I was transferred to Arya Girls High School as the headmaster. A male leading a girls' high school was an exception, but it turned out to be a very pleasant experience! I was promoted to the post of Senior Head and came to be affectionately known as the "Headmistress!" In 1991, of my own free will, I retired from teaching and migrated to Toronto, Canada where I took up teaching again. I have now finally retired from teaching but not from life.
