Sarah Hamilton FCA CTA


Sarah was educated at the Girls High School in Colchester before qualifying as a Chartered Accountant with BDO in Norwich in 1987. After two years working with BDO in Hong Kong Sarah returned in 1989, married Edwin, and began working for her father, Richard Sexton, in the practice he established and which he was devoted to for over 40 years until his sad passing in 2006. Shortly before the birth of the first of three children in 1991 Sarah passed the Chartered Institute of Tax exams and was made a partner in 1994. Sarah has a real interest in tax, finance and governance issues especially in family and owner managed businesses where taking an intelligent strategic view sensitive to personal circumstances is so important.

You might meet Sarah’s dog at the office as she is an animal lover with more than a few ponies and other creatures to look after, whilst enjoying being part of the rural community involved in village life.
