Mercer Advisors has crossed the $100 billion threshold in client assets, a milestone the Denver-based registered investment advisor attributes to organic growth rather than a flurry of acquisitions. The firm now manages approximately $110 billion for more than 42,000 families across the United States, with the pace of accumulation accelerating sharply. It took Mercer over three decades to reach its first $10 billion; it added more than that sum in the past 12 months alone.
CEO Dave Welling and president Daniel Gourvitch told InvestmentNews that the trajectory reflects families actively choosing the firm, not deal volume. "Our industry-leading organic growth is driven by more and more families choosing to build their family office with our teams," said Gourvitch. "The 42,000+ clients in the Mercer Advisors community today reflect a small percentage of the tens of millions of American families who we believe would benefit from our distinctive approach."
Founded in 1985 by tax and estate attorney Kendrick Mercer, the firm was among the earliest fee-based fiduciaries in the country. That heritage continues to shape its expansion strategy. Rather than operating as an aggregator, Mercer Advisors has pursued an integrator model, bringing partner firms fully into its operational and cultural structure rather than leaving them as standalone entities. Over the past decade, the firm has completed 117 such integrations, accepting fewer than 10% of firms that indicate interest in joining.
In 2025, its busiest acquisition year on record, Mercer brought in 18 new partner firms, entering markets including Oklahoma City and Greater Boston while adding capabilities in areas such as business management and tax services. The firm now employs more than 1,600 professionals nationwide, including approximately 1,100 client-facing team members and more than 420 wealth advisors supported by financial planners and specialists in tax, estate planning, investment management, insurance and trust administration. More than 200 professionals sit within the tax and estate function alone, supported by an investment team of more than 125.
The question of whether scale and personalization can coexist sits at the heart of Mercer's argument about its own model. Gourvitch said the answer lies in how local teams are structured and empowered. "At our core, we are a boutique that delivers personalized service to each of our clients. Our goal is to make every family feel like our only client," he said. "The key to boutique delivery is empowering local teams to make common-sense decisions for their clients. Each of our 40 markets consists of a team of ~25-30 professionals who collectively serve ~1,000 clients in their community and manage $2-3 billion of their wealth."
In the first quarter of 2026, more than 1,000 families chose Mercer Advisors as their family office, a figure the firm cites as evidence of strong organic momentum. Welling told InvestmentNews that the competitive environment has sharpened, but that Mercer's response has been to double down on reinvestment rather than cut corners. "The wealth management industry has never been more competitive, and our offering has never been more differentiated," he said. "We are attracting a record number of clients, particularly UHNW clients."
To serve clients across different wealth levels, Mercer formalized four service tiers in 2024 and 2025: Regis, Ascend, Custom Wealth and Wealth Path. Welling was pointed about the philosophy behind the segmentation. "The key to our segmentation approach is having advisors who focus on serving each client group. There are no 'B or C level' clients at Mercer Advisors," he said.
More than half of all Mercer employees now hold equity stakes in the business. The firm promoted more than 350 employees in each of the past two years, with 15% of financial planners advancing to wealth manager roles in the past year. Gourvitch said the ownership model reshapes how decisions are made internally. "When more than half your employees are equity owners, people make decisions with the long-term health of the firm in mind, because they're owners, not just employees," he said.
Looking ahead, Welling said the firm expects organic growth to outpace M&A, with the firm's breadth of capability serving as the key differentiator. The firm's integrator model and focus on client-first culture continue to attract top talent, even as the industry sees a wave of consolidation. For context, a recent Cerulli report noted that the RIA M&A pipeline has hit $3.9 trillion as the retirement wave accelerates, underscoring the competitive landscape Mercer navigates.
