Dennis Coyle didn't wait until after he had earned his applied-sciences degree to embark on his career: he founded DC Landscape Design & Construction in his sophomore year of college. He combined engineering know-how with knowledge gleaned from horticultural classes and years of work in a garden center and never doubted his capability to succeed in the landscaping business—perhaps because he wasn't the first Coyle to start so young. His father, Douglas Coyle, also transitioned straight from school to managing Delaware Valley Landscapers.
With an eye for outdoor aesthetics, Dennis beautifies lawns with an armory of mowers, aerating tools, and organic products. His botanical knowledge and detailed CAD plans help him avoid common landscaping mistakes, such as placing a young tree too close to a house or too far from its wailing mother. This understanding ensures an almost perfect survival rate for his relocated greenery.
