Arbor Knoll LLC., is a complete Design/Build landscaping firm established in 1985. In its infancy, it operated a retail establishment along with a nursery growing operation. Its core business was to supply landscape size nursery stock for its own projects along with sales to the surrounding communities. In 2000, Arbor Knoll decided to concentrate solely on Design/Build while continuing to supplement its projects with locally grown nursery stock from its nursery.

Arbor Knoll is a family-run business headed by William Lehmann and son Drew Lehmann. We pride ourselves on our creative, sustainable landscape designs, hand-picked specimen plant materials, extremely knowledgeable and professional staff, fine craftsmanship and superior service. Our strong educational background, along with lifetime careers in the nursery and landscaping industry, allows Arbor Knoll to provide its clients with creative, functional solutions for their site. In addition, our attention to detail, dedication to continuing education, and sincere desire to build trusting relationships place us in a category we believe to be second to none.

From conceptual design, to installation, to management and care of your grounds, we can ensure the integrity of your design through the years.
