Yellowstone Landscape promotes new CEO, CFO

Yellowstone Landscape promoted Harry Lamberton to the role of chief executive officer and Timothy Sherman to the role of chief financial officer. Current CEO, Tim Portland, will remain with the company in his new role as executive chairman.

More than two years ago, the company’s board of directors began planning for the next generation of the executive team.

“For most of the last decade, I was the sole pilot of our airplane,” Portland says. “For the last 16 months, I’ve been the senior pilot and the lead pilot, but Harry’s been the co-pilot and doing more and more to help fly the plane. And Timo Sherman’s been checking in on us to see how we are doing.”

Prior to joining Yellowstone as president, Lamberton served in numerous with Waste Management. Sherman previously served as vice president, finance at Yellowstone.

“I spent the last 30 years in the waste business and there are a lot of similarities,” Lamberton says. “What’s really important about our business is how field based it is and making sure that our branches are in a position where they can adapt and react to the marketplace.”

Lamberton adds a benefit of the change is Portland staying with the company. 

“One of the most appealing things we’ve got about moving forward is having Tim continued to be engaged,” Lamberton says. “The partnership that we’ve had and the way that we’ve been working over the last 16 months will continue.”

Yellowstone ranked number 4 on Lawn & Landscape’s 2023 Top 100 list with $539,000,000 in 2022 revenue.
