The Staffing Empire That Built His Fortune

William Stoller’s financial foundation was built on a staffing empire that spanned decades. As founder of The Stoller Group, he controlled 30 Express Employment Professionals offices across Oregon, Washington, Arizona, Nevada, and Colorado. This staffing network, part of the global Express franchise, positioned him as a leader in the temporary workforce industry. By 2025, filings indicated he earned approximately $10 million annually as CEO of Stoller Newport News, a subsidiary linked to his staffing ventures.

Stoller’s influence extended to Xenium HR, where he served as CEO and leveraged his staffing expertise to expand into HR solutions. The staffing industry’s growth from 2021 to 2026, coupled with his strategic leadership, solidified his net worth. Analysts attribute $500 million to $700 million of his wealth directly to these ventures, though this figure remains contested due to private company valuations.

The Stoller Group and Express Employment Professionals

The Stoller Group’s 30 Express Employment Professionals offices generated steady revenue through staffing services. By 2021, industry analysts highlighted these operations as the “primary driver” of Stoller’s net worth. His role as CEO of Stoller Newport News in 2025—where he earned $10 million annually—further underscored his dominance in the sector. The company’s filings and industry benchmarks suggest a consistent income stream, even as estimates of his total wealth fluctuated.

Xenium and Industry Leadership

Stoller’s transition to Xenium HR in the mid-2020s reflected his adaptability. Xenium’s focus on HR learning and payroll solutions expanded his staffing empire’s reach. While specific financial data for Xenium remains opaque, its integration into Stoller’s broader business network likely contributed to his $500M–$700M net worth estimate. However, this figure clashes with a 2023 report citing his net worth at $15 million, raising questions about valuation methods.

From Turkeys to Tasting Rooms: The Wine Legacy

William Stoller’s family legacy in Oregon’s Willamette Valley began in 1943, when his father and uncle purchased farmland for turkey farming. By the 2000s, Stoller transformed the property into the Stoller Family Estate, a landmark winery celebrated for its Pinot Noir. This venture, while culturally significant, contributes less directly to his net worth than his staffing empire. However, it underscores his dual identity as a business innovator and agricultural pioneer.

The estate’s success hinged on the region’s terroir: sloped, rocky terrain with low-yielding soil. Stoller’s background in enology and viticulture (University of California, Davis) enabled him to cultivate premium wines. While vineyard sales and tourism generate revenue, the wine industry’s contribution to his net worth remains secondary to staffing operations. Nevertheless, the Stoller Family Estate’s brand value and estate management practices reflect his broader business acumen.

The 1943 Farm to Vineyards

The Stoller family’s purchase of the Oregon farm in 1943 laid the groundwork for their agricultural legacy. Initially used for turkey farming, the land was reimagined as a vineyard by the 2000s. Stoller’s formal education in winemaking and hands-on experience in the Willamette Valley positioned him to capitalize on Oregon’s rising reputation for Pinot Noir. This transition from livestock to luxury wine production highlights his strategic vision.

Terroir and Brand Value

The Stoller Family Estate’s success is rooted in the Willamette Valley’s unique geology. Sloped, rocky terrain and low-yielding soil create ideal conditions for high-quality grapes. While vineyard sales and wine tourism contribute to his wealth, the estate’s primary value lies in its brand equity. As a cultural touchstone, it complements his staffing ventures by diversifying his portfolio and enhancing his public profile.

Net Worth Breakdown: $500M–$700M or Less?

William Stoller’s net worth estimates span a dramatic range: $15 million (2023) to $700 million (2021). This discrepancy stems from differing valuation methods. Analysts pegging his personal stake in The Stoller Group as the primary wealth driver cite the $500M–$700M range, while 2023 and 2025 sources suggest lower figures. The variance reflects challenges in valuing private companies and the volatility of staffing industry benchmarks.

His 2025 passing adds complexity. Posthumous asset management and estate distribution may have altered his net worth. While no updated figures are available, his legacy in staffing and wine ensures his financial footprint remains significant. The $10 million annual income reported in 2025 filings suggests ongoing revenue streams, but whether this translates to a higher net worth remains unclear.
