Mr Whittington, who is from Chobham and is a distant relative of former Lord Mayor of London Dick Whittington, takes over from Mrs Elizabeth Kennedy and began work on Friday 22 April.
He previously worked for KPMG, a firm providing Audit, Tax and Advisory services, where he was Partner-in-Charge of the Infrastructure, Government and Healthcare group.
The High Sheriff is appointed by HM The Queen to hold office for one year and is her representative of the judiciary in the county carrying out ceremonial duties.
The High Sheriff was historically a powerful local figure but still has law and order responsibilities such as officially installing judges and rewarding people who have helped the police in catching criminals.
Mr Whittington said: “I am very honoured to be given this role and during it I am keen to help young people get into work through apprenticeships, internships and work experience, particularly in the science, technology, engineering and maths areas while I am also looking forward to visiting various organisations throughout Surrey during my year in post.”
