"Ron and his assistant arrived on time to do some fall cleanup landscaping at my house. What would have taken me three days to do, plus hauling away the debris, took them under two hours. It was the very best money I ever spent - more so because I got to meet such lovely people, but also because they helped me a great deal. I will be calling them in the spring for a clean up and masonry work."

"Vinny is a very friendly and professional guy who we really enjoyed working with. The quality of his work is excellent- we used him for our sidewalk and refurbishing the rod iron railings. Overall positive experience with him and the final project turned out great! We would definitely recommend him and will be using his services again in future projects."

"Last spring I decided to build a new stone patio and kitchen and selected Elite Development to do our project. They were not the cheapest but it was clear to us that these guys know what they are doing. From layout, to construction, to final turf and plantings they knocked it out of the park. Could not be happier and would not hesitate to hire them again. Alan F"
