Curtis Banks' chief financial officer, Paul Tarran, has resigned and will stand down from the board by the end of 2019.
The self-invested personal pension provider stated this morning (January 9) it has started the recruitment process for Mr Tarran's successor who will retain his responsibilities until this process is complete.
Mr Tarran has been involved with Curtis Banks since its foundation nearly a decade ago and was appointed as chief financial officer in 2012.
During this time he oversaw the growth and eventual IPO of the business in 2015.
He said after ten years with the business he felt the "time is now right for me to take a step back".
Will Self, chief executive of Curtis Banks, said: "The board is grateful for Paul’s huge contribution to the Curtis Banks Group.
"He has played an important role as chief financial officer during a period when the business has grown from a start-up to one of the UK's largest independent Sipp operators.
"Paul has agreed to provide the support needed to ensure that a smooth transition takes place after a suitable successor has been identified."
The news comes after rival Sipp provider Mattioli Woods lost its chief operating officer Mark Smith after 19 years with the firm.
Mr Smith, who resigned late last year, also felt the time was right to move on. He is now looking for his next opportunity.
Last month, Martin Tilley also announced he was leaving self-invested personal pension provider Dentons after 33 years in office.
The former director of technical services has agreed to join an undisclosed wealth management firm after his employment with Dentons ends in January.
