Parkinson (pictured) will report to Pat Tomlinson, president and CEO of Mercer, and Chris Lay, CEO of Marsh UK. The reporting line will move from Lay to Lisa Quest when she takes up the role of Marsh UK CEO on 6 April.
He succeeds Benoit Hudon, who is leaving the business to pursue other opportunities and will work with Parkinson to support the transition.
Parkinson joined Mercer in 2007 and was appointed UK wealth business leader in 2022, with responsibility for the firm’s investments and retirement business. He began his career at Mercer as an investment consultant in London and has held a number of international leadership roles at the firm.
In his new role, he will lead the strategic development and execution of Mercer UK’s commercial strategy across its health and benefits, investments and retirement, and workforce and rewards businesses, and will work with Marsh leaders to deliver services to UK clients.
