Denison in the community: Good Shepherd Housing Foundation

Denison Landscaping in cooperation with the NHLA (National Hispanic Landscape Association) and RulyScapes, Alexandria Lawn Services, Epling Landscaping and Lawn Services, and Ruppert Landscape are designing and executing a landscaping makeover for a home for the mentally disabled run by the Good Shepherd Housing Foundation, a non-profit charitable endeavor.

By improving the grounds of one Good Shepherd home in Woodbridge, VA on the 22nd of April, we are working to create more pleasant, safe, healthy, and usable outdoor space for residents and staff, and assist the Good Shepherd Housing Foundation with an important demonstration project that they can use as a showcase in kicking off a new capital campaign on May 6 to raise the funds needed to rehabilitate all their buildings and grounds.

Celebrating 40 Years!

John Denison found that a way to make money to pay for college became a passion. He had a pickup truck named “Chuck” and a mower.

“He decided landscaping was the thing for him,” says Josh Denison, operations and human resources manager for the Ft. Washington, Md.-based operation and the son of the company founder. “His second year cutting grass, he had a customer ask him to plant some azaleas. He decided, ‘I like this planting stuff more than I like this maintenance stuff.’”

Four decades later the company has more than 250 trucks on the road, trucks that drove a combined 24 million miles last year. Employees laid 18,197,000 square feet of sod.

Denison Landscaping has big plans to celebrate its anniversary. The company will complete 40 green initiatives that range from efficiency savings to community service. Read the full article from Landscape Management magazine
