The Mather Group (TMG) has expanded its foothold in the US with the purchase of Pillar Wealth Management, a Walnut Creek, California-based RIA.

This move adds over $200m in assets to TMG’s books and represents its fourth acquisition in the San Francisco Bay Area.

Pillar Wealth Management is led by co-principals Hutch Ashoo and Chris Snyder, who bring over 36 years of experience in advising high-net-worth clients.

The firm services suite includes investment management, estate planning, retirement planning, as well as tax strategies.

Snyder stated: “Since our inception, we have been dedicated to goals-based planning and low-cost, tax-efficient investment portfolios designed to meet each client’s risk tolerance. TMG has a parallel philosophy to Wealth Management and a suite of services our high-net-worth clients will appreciate.”

The team of Pillar Wealth Management will continue to serve their clients locally.

TMG CEO Jennifer des Groseilliers said: “We’re excited to welcome the team at Pillar Wealth Management to The Mather Group. Together, we’re uniquely positioned to help more clients build financial strategies rooted in what matters most—their values, their families, and their vision for the future. Because we believe true wealth management starts with why, not just how.”

The acquisition is TMG’s 21st since 2018, and aligns with the firm’s wider strategy to strengthen presence across the West Coast, aiming to serve the high-net-worth and ultra-high-net-worth demographic.

TMG, a fee-only wealth management firm, has 12 offices across the US. The Chicago-based RIA aggregator managed more than $14bn in assets as of 31 March 2025.
