NEW YORK, Oct. 1, 2026 /PRNewswire/ — Cerity Partners, a leading independent wealth management and investment advisory firm, today announced that it has merged with Cornerstone Capital, Inc., a Palo Alto–based wealth management firm serving high-net-worth individuals and families as well as charitable foundations and endowments. The merger marks a deepening of the firm’s presence in Silicon Valley and adds approximately $1.4 billion in assets under management. The combined firms will operate under the Cerity Partners name.
“Cornerstone Capital has spent nearly 50 years building the kind of deep, multigenerational client trust that can’t be manufactured, only earned,” said Claire O’Keefe, Partner and Head of Partner Development at Cerity Partners. “The partners and colleagues at Cornerstone embody the culture we look for in every partnership: client-first, colleague-oriented, and deeply committed to doing right by the families and foundations they serve. We’re proud to welcome them to Cerity Partners and excited about what their presence in the Bay Area means for our clients and our partnership.”
Founded in 1978, Cornerstone has built its reputation over nearly five decades on close, high-touch relationships with clients anchored in disciplined investment management, financial planning, and estate and tax coordination.
“For almost 50 years, Cornerstone Capital has been guided by a simple principle: every decision we make is driven by what we believe is best for our clients,” said Brad Dinsmore, Partner at Cornerstone. “As we thought about the next chapter for our clients and our colleagues, we wanted a partner who would protect that philosophy while giving us more to offer. In Cerity Partners, we found a firm that shares our values and gives our clients access to resources—in tax planning, estate planning, and beyond—that we couldn’t offer on our own.”
