The Mather Group Acquires Resource Advisory Services

The Mather Group continues to build 2020 M&A deal momentum with third acquisition of the year.

CHICAGO--()--The Mather Group (TMG), a family- and employee-owned wealth management firm with seven offices across the country, announced today its acquisition of Resource Advisory Services, a Knoxville-based fiduciary-only firm with $116 million in assets under management (AUM). The Resource Advisory Services deal marks TMG’s sixth acquisition in the last 18 months, and third of 2020, bringing their total AUM to over $3.9 billion.

Resource Advisory Services is a comprehensive wealth management practice, providing clients with financial planning and portfolio management. This makes them a great fit for TMG, who has attracted like-minded fee-only RIA owners with their holistic approach. “TMG’s unrivaled technology platform and boutique culture really attracted us to their firm,” says Resource Advisory Services Founder David Lewis. “I’m thrilled to partner with a next-generation founder who isn’t private-equity backed, and feel very confident TMG’s long-term vision will support my advisors into the future. Every conversation has illustrated the harmony between our cultures of client service and business ethics,” he adds.

TMG Founding Partner Stewart Mather, age 42, who has been recognized as one of America’s Top 100 Independent Advisors by Barron’s, is excited to strengthen TMG’s footprint in the southeast. “David Lewis has been a leader in the Knoxville community for many decades. His commitment to a fee-only fiduciary approach, from the time fee-only financial planning began to be a known term, offers a tremendous foundation for TMG to grow in this market,” says Mather.

TMG provides comprehensive financial services to high net worth clients, including tax preparation, tax advice, portfolio management, concentrated stock management, estate planning, and comprehensive financial planning. TMG’s proven success in this space, driven by their innovative technology platform and in-house CPAs, recently landed the firm the number 14 spot on Forbes Top 100 Wealth Managers of 2019 and the number one spot on Financial Advisor Magazine’s Fastest-Growing RIA Firms.
