Corient acquires Rootstock Advisors to expand UHNW client services

MIAMI: Corient, one of the nation’s largest and fastest-growing national wealth advisors, announced on Thursday that it has acquired Rootstock Advisors, a Pennsylvania-based registered investment advisory firm with approximately $600 million in assets under management as of January 31, 2025.

This acquisition bolsters Corient’s ability to serve ultra-high-net-worth (UHNW) clients and extends its presence in the Pittsburgh region.

Since its founding, Rootstock has built a client-centric culture, catering to a select group of UHNW and high-net-worth families and households.

The firm offers comprehensive family office services, including investment management, estate planning coordination, philanthropic strategy, family governance, education planning, wealth planning, and income tax oversight.

Rootstock’s dedication to tailored solutions has fostered enduring client relationships and established the firm as a trusted partner in generational wealth preservation and growth.

“By joining Corient, we gain access to the expertise, resources, and support of a leading national wealth firm, which enables us to do more for clients,” said Greg Simpson, President of Rootstock.

“Corient’s unique Private Partnership was a critical factor in our decision to join, as it promotes an alignment of values across the firm and allows us to collaborate with a large and growing team of colleagues with significant experience and expertise.”

Kurt MacAlpine, Partner and Chief Executive Officer of Corient, added, “Rootstock’s expertise in serving ultra-high-net-worth families and deep commitment to providing bespoke family office-style solutions make them an exceptional addition to Corient.

We share a commitment to acting as trusted fiduciaries, providing solutions that prioritize clients’ interests and simplify the challenges of managing significant wealth. Together, we’re focused on exceeding client expectations, helping families navigate financial complexities, and building enduring legacies for the future.”

This acquisition marks Corient’s third transaction in the past three months. In January, Corient acquired the multi-family office business of Geller and Company of New York, and in December, the firm announced an agreement to acquire H.M. Payson & Co. of Portland, Maine.

These transactions follow Corient’s announcement on November 25, 2024, that it had entered into a definitive agreement with an affiliate of Mubadala Capital, the alternative asset management arm of Mubadala Investment Company, to take the firm private.
