Sebastian's working life started as a printer but at the age of 19, he started doing the Knowledge and passed out at the age 22. He has been a cab driver ever since.
His charity work with the Taxi Charity started in 2018 when he did his first trip to Normandy. He was bowled over by what he saw the charity do and when he was asked to join the committee, he jumped at the chance to be more involved.
He became treasurer of the Taxi Charity in 2019.
In 2021, he undertook the Three Peaks Challenge with another volunteer cab driver and raised £4,000; and in September 2022, he took part in the Market Garden Challenge in the Netherlands with fellow volunteer, Chris Wilmott, raising over £2,000.
Sebastian is interested in many different sports, as well as military history.
