Roy McLoughlin has left London-based Master Adviser after 19 years to head to Cavendish Ware.
The former partner of Master Adviser said he would be doing more protection and pensions business at Cavendish Ware, which is also based in London.
In particular, he said he would be working on auto-enrolment in his new role as associate director at the firm.
Mr McLoughlin said: "I felt it was time for a change in my career", having spent nearly 20 years at Master Adviser.
He commented: "I am looking forward to this exciting new challenge with Cavendish Ware, helping to spread the message that protection is a really important aspect of holistic financial planning to clients and the public at large.
"At the same time, I believe the auto-enrolment reforms really have marked a sea change in terms of pension provision in the UK.
"IFAs have a crucial role to play in getting the people of the UK to save enough for their retirement."
Mr McLoughlin expressed his gratitude to Master Adviser for the opportunity and all the support over nearly two decades of working at the firm, and said he looked forward to the new challenges ahead.
He added: "I would like to thank everyone at Master Adviser for the opportunity of working with them over the years.
"I look forward to working to spread the pension and protection messages in this next phase of my career."
In 2014, Mr McLoughlin also became a non-executive director of insurance specialist British Friendly Society.
