Partnership adds Portland-based RIA known for holistic, planning-first client service
DENVER, DECEMBER 10, 2025 – Mercer Global Advisors, Inc. (“Mercer Advisors”), a national Registered Investment Adviser (“RIA”), today announced the acquisition of Thompson Advisory Services (“Thompson Advisory”), a Portland, Oregon-based RIA firm managing approximately $260 million in client assets. The partnership strengthens Mercer Advisors’ presence in the Pacific Northwest, adding a like-minded fiduciary team to its growing presence in Portland.
Founded in 2009 by Troy Thompson, JD, Thompson Advisory provides holistic wealth management that integrates investment management, financial and estate planning, insurance and tax strategy—including tax preparation. Serving more than 90 families, Thompson Advisory’s four-person team delivers multigenerational guidance with a steadfast commitment to fiduciary standards.
“From day one, our focus has been to bring together every aspect of a family’s financial concerns under one roof,” said Thompson. “Mercer Advisors shares that same vision, while providing the scale, resources and technology to help us elevate how we serve our clients. By joining Mercer Advisors, we’re able to accelerate our growth without losing the personal connection that defines us.”
As part of Mercer Advisors, Thompson Advisory’s team will gain access to an expanded suite of integrated family office services, including institutional-grade investment management, estate and trust planning, tax expertise, and next-generation financial education.
“Mercer Advisors prides itself on being the place where advisors can do the best work of their careers,” said Martine Lellis, Principal, M&A Partner Development at Mercer Advisors. “After getting to know the Thompson Advisory team, it became clear that one of the challenges holding them back was a lack of enterprise-scale operations and fully integrated technology. With more resources and specialists at their disposal, the Thompson Advisory team has the opportunity to build lasting value for clients for generations to come.”
“Portland is a key market for Mercer Advisors as we continue to expand our presence in the Northwest,” added Jessica Caruso, Executive Managing Director at Mercer Advisors. “Troy and his team embody the fiduciary, planning-first philosophy we value in every partnership, and we’re excited to welcome them to Mercer Advisors. We look forward to supporting the Thompson Advisory team as they enhance their capabilities and deepen their impact in the greater Portland community.”
