A tree is a difficult thing to hurry. You can change its owner, reorganize the company that harvests it, or put its expected cash flows into a spreadsheet. The tree keeps its own schedule. That makes Northern California’s timberlands a useful place to begin a story about Sansome Partners, an investment firm whose central proposition is that ownership should leave room for time.
- Private investments plus a long-only public fund targeting 10 positions.
- Flexible ownership: debt or equity, controlling or minority stakes.
- A forestry connection that puts patient capital into practice.
Sansome was founded in 1997 by Sandy Dean, previously a partner at Blum Capital Partners. A year later, Fisher-family investors created Mendocino Redwood Company. Subsequent reporting identified Sansome as the vehicle through which the family controlled the timber business. Here was an investment with an unusually literal version of growth: leave more productive trees standing, and tomorrow’s asset might become more valuable.
What does patience cost?
The 1998 acquisition cost the Fisher family about $200 million, according to a later account in Yale Environment 360. That is the purchase price of the forestry investment, not a Sansome fundraising round. The other cost was less visible: accepting that some possible cash would remain in the woods.
In a 1999 interview, Dean described harvesting at roughly 50 to 60 percent of a conservative estimate of forest growth. The intention was to increase the stock of trees over decades. That meant evaluating the business over a longer period than its immediate profits might encourage.
“We may not make much of a profit in the short-term.”

This is where the phrase “long-term investor” acquires a price tag. Selling less today can preserve something worth owning tomorrow. Whether the trade succeeds depends on operating costs, future demand and the asset itself. A patient owner still needs a sound business.

Two portfolios, a wider choice
Sansome’s current investment business reaches beyond timber. It reports deploying billions of dollars of private-equity capital since inception. Alongside those investments, it manages a long-only public-equities fund targeting 10 positions. The contrast is useful: a broad choice of investment types, paired with a deliberately concentrated public portfolio.
The private mandate spans domestic and international opportunities, public and private companies, debt and equity, and controlling and minority ownership. For a business considering an investor, those distinctions matter. A loan, a minority shareholder and a controlling owner create different obligations and relationships.
The firm says its capital forms part of a larger pool. Its stated approach lets portfolio-company managers work without pressure to hit short-term targets. The proposition for an owner is therefore partly about governance: what will the shareholder ask management to optimize, and over what period?
Sansome earns its place in the market as an investment owner and capital allocator. The relevant alternatives include buyout funds, family investment offices and public-equity managers. Its website explicitly excludes advice and securities sales to the investing public. A retail saver looking for an account-opening button is outside its stated audience.

The forest did not win everyone over
The early forestry story contains friction. Protests followed Mendocino Redwood’s logging plans. A November 2000 Ukiah Daily Journal report said the Forest Stewardship Council had denied certification the previous year before granting it in 2000. Certification imposed conditions for continued improvement. Some local environmentalists remained unconvinced.
That sequence matters because an owner’s intentions and a community’s confidence are separate things. A new shareholder could announce a longer horizon immediately. Demonstrating different forest management required changes that other people could inspect.
The operator’s historical fact sheet describes eliminating traditional clearcutting in fall 1998, adopting partial-harvest approaches and protecting old-growth trees under its policy. UC Berkeley later featured Dean discussing the transition to certified management and the social challenges of changing forestry. These were operating decisions, rather than a new slogan for the same harvest.

Count what stays
Mendocino Redwood’s activity sheet, published in February 2026, reports conifer inventory rising from 2.1 billion board feet in 1998 to 4.6 billion at the end of 2025. It also records 958.5 million board feet harvested over that period. Standing inventory increased while the business continued cutting timber.
Operating inventory, not investment performance.
Those are company-reported operating figures. They do not establish Sansome’s returns or settle every ecological question. They do, however, measure something central to the original proposition: how much forest inventory remained after years of commercial activity.
A 2024 UC Agriculture and Natural Resources profile adds another practical detail. Forest policy director John Andersen described how the 2020 CZU Lightning Complex fires made the wildfire threat tangible. Mendocino and Humboldt Redwood prepared fire-risk analyses and became more proactive about fuel reduction, including prescribed-fire projects.
Here, the long-term plan had to respond to a changing threat. Andersen also described growing legislative support for funding fuel reduction after destructive fires. His account concerns forestry operations and public policy, rather than a reversal of Sansome’s investment philosophy. It shows why a long holding period still requires decisions along the way. Waiting leaves an owner exposed to whatever happens during the wait.
The people making those judgments bring a range of financial backgrounds. Sansome’s team biographies include Sorina Casian-Botez’s experience at Eight Roads and Bain, Davis Liu’s work at Blackstone, and Sean Haechler’s corporate-finance and restructuring experience at FTI. Those are specific sources of expertise for evaluating a business, its ownership and its financing. The biographies provide a clearer picture of the firm’s capabilities than a generic promise of investment discipline would.
Give the asset the right clock
For a business owner, Sansome’s approach suggests asking a prospective investor a concrete question: can its capital remain available for as long as the plan requires? For an investor, the useful habit is to define evidence of progress before deciding how frequently to judge it.
Neither lesson makes waiting sufficient. A concentrated stock portfolio magnifies mistakes; an illiquid asset can become a problem when its owner needs cash. The forestry example is most useful when read with those conditions attached. Sansome’s proposition asks owners to consider whether their financing timetable gives a good operating plan enough time to work.
