In 2011, Stewart Mather left Morgan Stanley with $150 million in assets under advisement (AUA) to establish a fee-only fiduciary firm that would serve affluent and ultra-affluent individuals and families. At the time of Stewart's passing in 2020, TMG had grown to more than $6.8 billion in assets under advisement (AUA) and $5.6 billion in assets under management (AUM). The firm had expanded from its Chicago headquarters to include offices in and around Atlanta, Austin, Dallas, Houston, Knoxville, and Philadelphia, along with a presence in the San Francisco Bay area. The Mather Group, LLC (TMG) is one of the fastest-growing independent, fee-only registered investment advisory firms in the country, offering comprehensive financial planning services with their clients’ best interests in mind.
