The de Jong name, synonymous with the waste industry, has long been associated with hard work, ethics, fairness and loyalty. Ask anyone and they will tell you that Eric de Jong, owner of Diamond Environmental Services is an honest, hardworking ethical family man of great character.

Eric's father, Arie de Jong, knows first hand that hard work builds character. His own hard work turned Coast Waste Management, a company he picked up at auction, into a well established refuse removal company. Raised with the same beliefs and following in his father's footsteps Eric has built a medium sized highly respected empire.

December 2007 marked Diamond's 10th Anniversary, a major milestone that allows Eric and Operations Manager, Warren Van Dam, to lean back in their chairs and reflect on the challenges they faced to bring Diamond to where it is today.

With fondness Arie de Jong, Eric's father, recalls the day he sold Coast Waste. "Eric had only worked for me you know, and I thought he should experience the corporate structure, so I encouraged him to stay on at Coast with the new owners." Smiling he adds, "Eric only stayed with them for three months. He's always been a people person and he suddenly found himself in meeting after meeting and with no time for sales or customers. It bothered him that customers weren't taken care of the way we had always taken care of them. Eric has always been a people person."

Eric along with Operations Manager Warren Van Dam knew from day one that they would be the best portable restroom rental company in Southern California. Both Eric and Warren worked long hard days to establish Diamond as a reputable company. The company of choice, Diamond started out a two truck, one route operation with Eric filling the role as the company’s only sales rep and Warren driving the route truck. 

Both are proud of Diamond’s facility, staff and reputation, referred to by others in the industry as “the cleanest restroom facility in the country.”

Eric's dedication to customer service and Dutch clean continues. "I have never felt that customers are just accounts…" he says before adding, "Every customer we have the honor of serving is one of many critical and important clients that are the very foundation of Diamond, its history, and its future."
