Greg Guzman, the owner of Bill Dunlop Lawn Services is a true professional. We subcontract for some of his commercial properties taking care of the trees. What I like the most about working with Greg is his commitment to doing things the right way. Many landscaping firms the size of Greg’s don’t care about ANSI standards, pruning correctly as it relates to our capabilities, and Greg epitomizes the true sense of holding to high standards. He’s tuff and a joy to work with!
