Gillian Davies has been appointed to the role and will join the board with immediate effect.
As the firm revealed in April, current CFO Nick Bravery will step down from the board with effect from 31 October, facilitating an “orderly hand-over” before assuming the position of company secretary on 1 November.
Ms Davies has more than 14 years' experience as a finance director across listed and private businesses, including 11 years as group finance director of FTSE listed 4imprint Group plc.
She is qualified as a Chartered Accountant, with KPMG in 1992.
Peter Mann, chairman of Harwood Wealth Management Group, said: “I am delighted to welcome Gillian to the group and look forward to working with her.
“She has an excellent track record of delivering sustained growth in shareholder value and we are confident Harwood will benefit from her strong financial control and experience working with high growth companies.”
