Mr Brown joined the financial services company in January 2019 as Financial Controller.
“Tristan has proved himself to be a valuable member of the finance team and an extremely capable financial controller so it was a natural progression for him to take on the role,” said Group Managing Director Mark Bousfield.
In his new role, Mr Brown, who qualified as an accountant in 2017, will manage the finance team, prepare the group annual and interim reports, budgeting and cash flow forecasting and have oversight of the monthly reporting.
He said: “The size of the group and range of services that Ravenscroft now offers makes this a challenging but very rewarding role but it’s a fantastic opportunity.”
