Recognition places TMG among the nation’s Top 50 RIAs and reflects the firm’s continued focus on client-centered growth.

The Mather Group, LLC (TMG), a $17 billion leading wealth management firm serving high-net-worth individuals and families nationwide, today announced that it has been ranked No. 41 on Barron’s 2026 Top 100 RIA Firms, placing TMG among the top 50 registered investment advisory firms nationally.

The recognition comes as TMG continues to thoughtfully expand its national presence and capabilities while maintaining a planning-led approach centered on helping clients navigate increasingly complex financial lives. Throughout that growth, the firm has remained focused on providing personalized advice and greater coordination across financial planning, investment management, tax strategy, and estate planning.

“Being recognized by Barron’s is a reflection of the deliberate way we’ve grown TMG and the team behind that progress,” said Jennifer des Groseilliers, Chief Executive Officer of The Mather Group. “I’m incredibly proud of the work our team has done to get us here, and even more excited about what we can continue to build together in the years ahead. As TMG continues to grow, our focus remains on building the capabilities and expertise that allow us to serve clients more comprehensively while preserving the personalized experience and relationships that are central to our firm.”

Over the past 18 months, TMG has completed five RIA partnerships, broadening its presence across California, Oregon, New Jersey, and Illinois while strengthening specialized capabilities for business owners and high-net-worth individuals. As the firm has grown, its Why-Powered Wealth Management approach has remained central, bringing together deeper expertise and broader resources to help clients align financial decisions with their values, goals, and aspirations.

Barron’s 2026 list marks the publication’s 11th annual ranking of independent advisory companies.
