Fitzgerald will remain in post as group finance director, but will hand over the CEO title to Lam, formerly group managing director, on 6 September.
Both have held their respective roles at the firm for the past 10 years.
Fitzgerald said: “It has been a privilege to have served as CEO and to have seen the organisation grow significantly to the next level as a fully-listed independent investment/wealth management group, which is now well positioned for the next phase of growth under Sean Lam’s leadership.”
The management shake up also sees Mark Rushton, who joined the firm five years ago as chief investment officer, take on the role of CEO of the investment management and stockbroking arm, Walker Crips Stockbrokers, previously held by Lam.
David Gelber, Walker Crips’ chairman, added: “Rodney has done a tremendous job in leading the business for over 10 years as CEO and has played a pivotal role in managing the transformation of the group from private client stockbrokers into an integrated investment and wealth management house.
“His successor, Sean Lam, has already played a key part in the success of the group, previously as CEO of Walker Crips Stockbrokers and as group managing director with dual responsibility over group operations and technology, making him the ideal person to lead Walker Crips into the future.
“Rushton has also been instrumental in our recent rapid growth, attracting a series of new teams of advisers to the Group since joining in 2012, which has changed the quality of our revenue streams and enhanced the processes and culture throughout the organisation.”
