Get to know a new kind of adviser

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 our clients’ best interests in mind.

TMG is registered under the Investment Advisers Act of 1940 as a Registered Investment Adviser (RIA) with the Securities and Exchange Commission (SEC). This means we have a fiduciary duty to always act in our clients’ best interest. When clients choose TMG, we work to mitigate any potential conflicts of interest regarding how their money is managed and where their money is held. Our financial professionals do not hold brokerage licenses, are not compensated by selling products, and do not earn commissions—we do not incentivize ourselves at our clients’ expense. We aim to minimize cost wherever possible and to provide complete transparency about our fees, which are outlined in our firm’s public disclosure documents.

We educate investors on what the fiduciary responsibility really means, at a time when it is more important than ever.

“The Mather Group’s focus is exclusively on our clients and their success.”
We believe in giving back to the communities we serve.

1978 - 2020

In a highly distinguished career, Stewart Mather founded TMG out of a passion for providing clients a clear path to retirement and ensuring them a fulfilling "second act".

In 2011, Stewart left Morgan Stanley with $150 million in assets under advisement (AUA). Today, TMG has grown to more than $6.8 billion in assets under advisement (AUA), and $5.6 billion in assets under management (AUM). Headquartered in Chicago with offices in Atlanta, Austin, Dallas, Houston, Knoxville, the Philadelphia area, and a presence in the San Francisco Bay area, Stewart built a fiduciary-only firm over the last nine years serving affluent and ultra-affluent families and individuals.

In September 2020, Barron's ranked TMG in its 2020 list of the top 100 RIA firms in the United States. Stewart eventually was named by Barron's as one of the Top 100 Independent Financial Advisors in the U.S., and in 2018 was recognized on Forbes' 2018 Top 250 Advisor list and the Financial Times Top 300 Financial Advisers list for three consecutive years. TMG was recently named one of 2020’s Top 15 RIA Leaders by Financial Planning, claimed the number one spot on Financial Advisor Magazine's Fastest-Growing RIA Firms in 2019, and ranked 14th on Forbes Top 100 Wealth Managers list in 2019.

His resume tells only a part of the story. As all who knew him can attest, Stewart was one of the kindest most decent people who walked through the doors of TMG, with no ego and only the enthusiasm to drive the business to deliver the best possible experience to clients. He touched many lives with his wisdom, humility, and generosity. He was committed to the very highest principles of integrity, fairness, and TMG being a family and employee-owned wealth management firm.

Stewart displayed courage, humor, determination, and an unforgiving spirit, while enduring surgeries and treatments to battle his Cholangiocarcinoma or Bile Duct cancer. While growing TMG, he exhibited these same characteristics which helped to build a world class leadership team to carry-on his vision and legacy for the firm and its clients, should he ever pass. As a result, Stewart recognized that it was time to institutionalize the business and strengthen its executive structure and in 2019 brought on Chris Behrens to be CEO stating that "With plans to expand into five new markets in 2020, Chris's leadership will position the firm for our next phase of strategic growth. His proven track record and breadth of experience in scaling businesses through technology, innovation, and organization design and structure will be a great asset for The Mather Group." Going forward, Chris will continue to work closely alongside the entire TMG team to build on the strong momentum driven by the firm's core business.

TMG itself is part of Stewart's legacy. His passing is a loss for his family, for all his former colleagues, for the wealth management industry, and his loved ones and friends. We will forever be grateful for the examples he set for all of us and know that his spirit will live on.

With our deepest thanks and most caring thoughts,
