The Mather Group has been recognized by Barron's as one of the top registered investment advisory firms in the country. In a recent Q&A article “For Ultrawealthy Clients, a Host of Services Under One Roof,” Barron’s sat down with TMG for a conversation highlighting what sets the firm apart. In the piece, TMG CEO Jennifer des Groseilliers, CFO Ryan Wickert, and COO Kristen
Oziemkowski discussed their team-based approach, the firm’s growth through 25 strategic partnerships since 2019, and its commitment to comprehensive, integrated planning for high-net- worth individuals and families.
At the center of that conversation was the key value TMG brings to our clients. When you work with us, you don't get just one advisor, you get The Mather Group. You’ll benefit from personalized service supported by a dedicated team of specialists across financial planning, investments, tax strategy, and estate planning, so the right expertise is always available when you need it.
That approach is rooted in our why-powered philosophy. We believe the best financial decisions don't start with a marketprediction—they start with understanding what matters most to you: your values, goals, and vision for your future.
As a fee-only fiduciary firm, our commitment is the same for every client: comprehensive, coordinated planning that puts your best interest first.
