Pi Trustees has acquired Fairfield Trustees in a bid to expand its business and increase its geographical coverage.
Pi head of trusteeship Roger Cooper said: "This acquisition complements our existing trustee company, increases our geographical coverage and demonstrates our commitment to the independent trustee market."
Cooper added: "We have no doubt that the integrity and highest possible standards of professionalism demonstrated by Fairfield as trustees will make Jennie Croxall and Sarah Marshall invaluable additions to the Pi team."
Pi Trustees said Robert Garvin would assist with the changes and remain with the business for a short while following the deal.
Fairfield Pension Trustees traces its roots to 1991 when Robert Garvin founded Garvin Trustees.
Initially Garvin Trustees Limited formed part of Garvins Consulting Actuaries which was acquired by Barnett Waddingham in 2008. Garvin Trustees continued as an independent company wholly owned by Barnett Waddingham until 2012 when the trustee business was hived off to form Hanover Independent Trustees.
Hanover Independent Trustees was renamed Fairfield Pension Trustees Limited in 2016.
