Mr Rushton, 39, has worked in financial services for more than 18 years and joins from Financial Planning firm Citimark where he looked after high net worth clients.
In his new role, Mr Rushton, who specialises in retirement and estate planning, will be based at the Wells, Somerset office and join the wealth management team providing advice to high net worth clients nearing or at retirement.
Mr Rushon said: “Old Mill’s fantastic reputation for providing professional private client services in the South West, its commitment to going well beyond regulatory standards and its culture - which centres on delivering an exceptional client experience - hugely influenced my decision to join.”
Paula Hodge, head of wealth management at Old Mill, said: “It is actually quite rare to find someone like Neil, who has so much experience and whose beliefs and values are synonymous with Old Mill’s, so we are thrilled he is joining us.
“Having worked in a regional Financial Planning firm, a national accountancy practice and a private bank, Neil will be able to bring valuable insight and new ideas to help us further enhance our client experience.”
