Doug Black and the art of gaining ground

In 1984, Doug Black carried a football 264 times for Army and gained 1,148 yards. Divide one number by the other and you get a little more than four yards per attempt. It is an unglamorous unit of achievement, particularly in a sport that packages its memories as spectacular catches. But four yards, repeated often enough, can make an afternoon very inconvenient for the opposition.

Black set Army’s single-season records for rushing yards and attempts that year. Under coach Jim Young, he shared the backfield with quarterback Nate Sassaman. They became the school’s first pair of thousand-yard rushers in the same season. The team finished 8-3-1 and beat Michigan State 10-6 in the Cherry Bowl. Those were collective results, with a fullback’s substantial contribution inside them.

Today Black is chairman and chief executive of SiteOne Landscape Supply, based in Roswell, Georgia. His customers’ working vocabulary includes irrigation fittings, nursery stock, fertilizer and stone. It is another business where progress depends on several people doing their part, and where a missing component can spoil everybody’s afternoon. The comparison is an editorial one; Black’s career provides the particulars.

His route to the executive chair passed through Army construction projects, business school, consulting and building materials. Along the way, the scale changed considerably. The practical question remained recognizable: how do you assemble people and resources so that work actually gets done?

A mathematician in the backfield

There was academic substance behind the football uniform. Black studied mathematical science and civil engineering at the United States Military Academy. In 1985, he was recognized as a National Football Foundation National Scholar-Athlete. His 3.48 mathematics GPA and six terms on the Dean’s List gave that honor something firmer to stand on than a good highlight reel.

His career totals at West Point reached 2,098 rushing yards and 16 touchdowns on 461 carries. Consider those numbers alongside the academic record and a more useful picture emerges than the familiar athlete-turned-executive shorthand. Black was already doing two demanding things at once, one scored on a field and the other in a classroom.

After West Point, he served as an Army engineer officer from 1986 to 1990, completing construction projects in the southeastern United States and in Central and South America. Engineering gave him work with a physical destination. At some point, plans had to become something that existed outside the plans.

He then attended Duke University’s Fuqua School of Business, earning his MBA in 1992 as a Fuqua Scholar. That same year he began his business career at McKinsey & Company. His assignments covered strategy, sales-force effectiveness and plant improvement across telecommunications, airlines, lumber, paper and packaging. It was a broad education in the gap between an attractive business idea and a functioning operation.

Eighteen years among the materials

Black spent 18 years at Oldcastle, the American building-materials business owned by Ireland’s CRH. He led its entry into building-products distribution and moved through operating and chief executive roles in its architectural-products and materials businesses. Before leaving, he was president and chief operating officer of Oldcastle Inc.

Distribution is easy to underestimate from a distance. The finished patio earns the photograph; the supplier earns a question about whether the remaining stone will arrive on time. Black’s Oldcastle years placed him inside the businesses that connect production with the people doing the building. His later move into landscape supplies kept him close to that practical exchange.

In April 2014, he became chief executive of John Deere Landscapes. Clayton, Dubilier & Rice had announced its agreement to buy a majority stake in the business the previous October. Black arrived at an established operation entering a new phase of ownership, with the task of developing its capabilities as a standalone company.

He brought experience in running material-heavy businesses and in expanding distribution. The job also required colleagues with different specialties. By the time of the public offering, the leadership team had added expertise in areas including technology, supply chain, marketing and talent management. The work extended well beyond the person whose name appeared beside “CEO.”

The new sign on an old business

On October 19, 2015, John Deere Landscapes became SiteOne Landscape Supply. The name and the “Stronger Together” tagline were introduced at the industry’s GIE+EXPO in Louisville, Kentucky. A rebrand is a moment when a business must explain itself afresh, even to people who already know where the loading entrance is.

Black’s explanation emphasized continuity. The company had a history and relationships that could not be replaced as casually as a sign. There is an appealing modesty in that distinction: a chief executive can introduce a name without claiming to have invented the people, knowledge and customer trust beneath it.

His stated ambition was to help customers become more successful landscape professionals. He put the collaborative part plainly: “By working together with our suppliers and customers we can achieve great things.” The sentence is short. The operating obligations it creates are considerably longer: buying, stocking, advising, delivering and getting the next order right.

SiteOne began trading on the New York Stock Exchange on May 12, 2016, under SITE. Black became board chairman in June 2017. Those dates mark his progression from the leader hired for a newly independent business to the executive overseeing both its operations and its board. An exchange ticker gave the story a public scoreboard, with reporting dates that arrive whether or not the weather cooperates.

“By working together with our suppliers and customers we can achieve great things.”

The people inside the purchasing power

Black’s public description of SiteOne’s ambition has five constituencies: employees, customers, suppliers, communities and shareholders. In his 2024 impact-report letter, he called those objectives the company’s “True North.” The aspirations cover a good workplace, useful service, supplier relationships, community responsibility and financial results. They also give readers several ways to judge his performance.

One practical example was the addition of more Spanish-speaking associates at branches to serve customers. It is an ordinary detail, and therefore revealing. A distribution network works through conversations as well as inventory. Being understood at the counter belongs alongside having the right product behind it.

The acquisition of Reinders in March 2026 supplied another test. Reinders was a fifth-generation family business, with 12 locations across six Midwestern states and more than 150 years of history. Its expertise ranged across irrigation, agronomics, lighting and landscape supplies. SiteOne was purchasing a network of knowledge and relationships as well as places to store products.

For Black, the challenge in such a deal is visible in the thing being acquired. Technical advice, local familiarity and customer confidence are valuable precisely because they have taken time to accumulate. A larger organization has to give that experience somewhere useful to go. Purchasing power is easier to describe in a presentation than the judgment of an experienced employee facing a complicated customer question.

A harder season, still a working plan

The recent numbers give the profile some necessary friction. In the second quarter of 2026, SiteOne recorded $1.531 billion in net sales, up 5% from a year earlier. Organic daily sales increased 1%. Acquisitions contributed approximately three percentage points to sales growth. These measures describe different parts of the business; treating them as interchangeable would make the picture tidier and less useful.

The quarter’s net income attributable to SiteOne was $139.3 million, an 8% increase. Black described softer end markets, while discussing operational improvements and control of spending. Growth during weak demand is a different assignment from growth with a strong market behind it. His responsibilities include making room for expansion while dealing with the costs of the operation already in place.

Expansion continued. In August, SiteOne’s Devil Mountain Wholesale Nursery subsidiary acquired Patterson Nursery Sales, an Oregon grower and distributor. Black described the deal as extending the nursery business in the Pacific Northwest and improving its ability to distribute products nationally. The announcement tied the purchase to geography and product capability, giving the strategy a concrete address.

As of October 23, the next scheduled public checkpoint was October 28, when SiteOne was due to report third-quarter results. That leaves the narrative appropriately unfinished. Black has been chief executive since 2014, but tenure does not cancel the next quarter’s questions. A fullback’s old arithmetic offers a useful way to read an operating career: look at the ground gained, then look at how it was gained.

The class that stayed connected

West Point has remained part of Black’s public life beyond the biography paragraph. In 2016, Army named him among the honorary captains for its spring football game, alongside former teammates including Sassaman. Returning in that role put a business executive back among people who had known him when the relevant title was fullback.

He also serves on the volunteer board of the Johnny Mac Soldiers Fund. The organization grew out of the West Point Class of 1986’s response to the death of classmate Colonel John “Johnny Mac” McHugh in Afghanistan in 2010. Formally established in 2014, it provides educational scholarships to military families, with particular attention to children of fallen service members.

That work supplies a personal connection between Black’s own education and the opportunity of another generation. A scholarship has a different timetable from a quarterly result. Its value can keep unfolding long after the payment clears. The commitment also places him among fellow veterans and business leaders working on a shared obligation outside their companies.

Football statistics, construction assignments, a new company name and a scholarship board can seem like separate entries on a résumé. Together, they make a more particular portrait of Doug Black: someone whose working life has repeatedly involved organized groups trying to move something forward. The objects have included a football, building materials and the means to attend college. The work has acquired larger numbers. It still has people in it.
