ST. LOUIS, MO / ACCESS Newswire / November 17, 2025 / Matter Family Office and IWP Family Office announced today that they have merged, uniting two organizations with a shared commitment to serving ultra-high-net-worth families. The unified firm will continue to set the standard for an integrated, "forever" multi-family office that helps multigenerational families grow wealth, align decisions with their values, and manage day-to-day finances with care and continuity.

The combined firm creates a platform that blends deep public and private investment expertise, comprehensive family office services, and a proprietary culture & learning offering. Together, the firms serve over 140 families nationwide with over $10 billion in assets under advisement¹.

The merger brings together over 90 professionals across offices in St. Louis, Denver, and Dallas-Fort Worth, with integration focused on continuity, collaboration, and client-centered results.

Leadership of the combined firm includes Katherine Lintz, founder and managing member of Matter Family Office, who will serve as managing partner, and Charlie Willhoit, founder and president of IWP Family Office, who will serve as chief executive officer and managing partner.

The transaction was funded by BW Forsyth Partners, an investment firm with an evergreen capital base and a track record of supporting founder-led businesses. Forsyth's investment supports the strategic combination of Matter and IWP, enabling the creation of a scalable, differentiated platform designed to meet the evolving needs of multigenerational families.

"This merger is about expanding our ability to serve families with greater breadth and depth," said Lintz. "IWP brings complementary expertise that enhances the way we support families for generations to come."

"Joining forces with Matter Family Office and partnering with a long-term capital partner in BW Forsyth is an incredible next step in the evolution of our firm," said Willhoit. "With the combination of IWP and Matter, we are bringing expanded UHNW investment services, in-depth family office administration, and proprietary family-centric learning and communication programs under one roof. The ability to integrate these pillars of family office management and execute for our clients is game-changing."
