Jon is the Founder and Chief Executive Officer of the MAC Group.
He established MAC Group in 2004, following a management buy-out of Aon’s Isle of Man financial advice business.

His visionary approach and commitment to strategic development have shaped MAC Group into a comprehensive provider of client-focused financial and insurance solutions.

A respected business leader, Jon has served as a Non-Executive Director on the boards of some of the Island’s most prominent companies. Recently, Jon extended his community involvement as a School Governor at King William’s College.
Jon works closely with Ed, Head of Private Client Advisory; Rebecca, Head of Corporate Client Advisory; and Ann, Group Broking Manager. He has a keen interest in technology and exploring innovative ways to keep MAC at the forefront of the industry in the Isle of Man.
