About Duke's

Landscape Management, Inc.

Duke’s Landscape Management was established in 1986 with a goal of developing into an industry leader. We have grown every year since our inception, now servicing over 7,000 condominium units and over 1,100 acres of commercial and residential properties from two offices. We are on the cutting edge of new technology; regularly attending seminars and trade shows throughout the country. We do not “make a sale,” or “fill a job opening.” We strive to build long-term relationships with our clientele and employees.

Eric Cross

CLT, CLP, Owner, President

Eric started the company in 1983 while still a sophomore at Delaware Valley College. After graduating in 1985 with a BS in Ornamental Horticulture and Minor in Business, he steadily grew Duke’s Landscape Management into an industry star in New Jersey. Eric has always played a major role in trade associations both state and national. Eric is one of the few individuals in New Jersey to hold the Certified Landscape Professional Certification, which is only attained after passing an extensive exam on insurance, risks, and business law. In 2011, Eric earned his LEED Green Associate Designation from the U.S. Green Building Council (USGBC). Eric’s goal with Dukes has always been to build and maintain a professional company where its clients and staff feel respected and appreciated. In addition to running a successful company, Eric also finds time to the volunteer in the community.
