CHICAGO--(BUSINESS WIRE)--The Mather Group, LLC (TMG), a $17 billion leading wealth management firm serving high-net-worth individuals and families nationwide, is proud to announce its inclusion on Crain’s Chicago Business Fast 50 list for a sixth consecutive year.

The annual Crain's Fast 50 ranking recognizes the fastest-growing companies headquartered in the Chicago area based on five-year revenue growth. Companies must meet rigorous eligibility requirements, including sustained revenue growth, profitability, and operational independence, to be considered for the ranking.

"Being recognized on Crain's Fast 50 list for the sixth consecutive year is a reflection of the trust our clients place in us and the dedicated work from our team," said Jennifer des Groseilliers, CEO of The Mather Group. "Over the years, we have continued to invest in our people, technology, and integrated planning capabilities so we can better serve clients and help them align their wealth with what matters most. We're honored to be recognized alongside so many outstanding companies helping shape the future of Chicago's business community."

Founded in 2011, TMG has grown from approximately $150 million in assets under management to more than $17 billion of assets under management and advisement across 14 offices nationwide. The firm's continued growth has been driven by its commitment to delivering comprehensive wealth management solutions through an integrated approach that brings together investment management, financial planning, tax strategy, estate planning, and family office services.

Over the past several years, TMG has continued to expand its national footprint through strategic partnerships and investments designed to enhance the client experience. In 2025, the firm expanded its presence in Northern California, the San Francisco Bay Area, and the Pacific Northwest through a series of strategic alliances. Most recently, TMG partnered with local Chicago firm Sebold Capital Management to expand its capabilities serving business owners, further strengthening the firm's integrated approach to wealth management.

At the center of TMG's growth is its belief that wealth management should be driven by purpose. Through its Why-Powered Wealth Management approach, the firm helps clients align their financial decisions with their values, goals, and aspirations, delivering personalized guidance that simplifies complex financial lives and provides greater clarity and confidence.
