He taught geography and science in Nelson and Redcar, during which time he would voluntarily undertake extracurricular activities after school hours and weekends introducing his students to the mountains.
With the assistance of a grant made by the then Sports Minister Dennis Howell, he was able to build the canoe training pool, extend the dry ski slope and provide a Bar which added greatly to the existing facilities of the Centre.
He ran (with the aid of his wife, Eileen Jackson) countless treks to the Himalaya, Zanskar, Kashmir, Nepal, India, Peru, Ecuador & Galapagos Islands, Kilimanjaro.
It is important to relate that he did not do this for money – he received no payment for these services as he considered it his "hobby" – he did this work for the love of travel, for the people who wanted to experience the mountains he held in such high regard.
