“When I made the decision to start this company, one thing was very clear to me – I knew there was absolutely no advantage, competitive or otherwise, to simply adopting ‘accepted industry practices’.

“I think the people we do business with – both directly and indirectly – will agree that we’ve always been noted for innovation. And, as we’ve proven over more than a decade, our innovative practices translate not only to increased efficiencies and cost savings, but to enhanced quality assurance as well.

“From the outset, I was determined to build this company on the strength of our expertise, our reliability, and our absolute integrity. And, in a very real sense, those qualities continue to reflect what SDE is all about.”

Stacey DePasquale, P.E., BCEE, CPSWQ, President
