I & S Landscape Supplies is a division of Simonson Concrete Const. In 1995, Simonson Concrete Const. was established by John Simonson, as one of the first concrete contractors in the area to specialize in decorative concrete. After 10 years of providing service to produce quality concrete foundations and flatwork for residential and commercial projects, Simonson Concrete relocated to a larger site in 2005. After the move to its current location, Simonson Concrete decided to create more offerings for the community by selling landscaping materials. Thus, the division of I & S Landscape Supplies was created and has expanded into the largest selection of landscape supplies in the area. In 2020, our 25th year of business, Ian and Sydney Simonson have decided to join John and Jan in providing service to our valued customers into the future.
