He started the business as a small 2-man operation and it has since grown steadily over the years to now employ over 45 people.

Mick Greenberg

Specialty Services Manager

Years ago, I lived in northern Wisconsin and I had a friend who had a lawn mowing business. He somehow picked up a bigger new property to maintain, the old, run-down local cemetery. Since my buddy was basically a one-man company, he was begging me to come help him at the cemetery. I told him no several times. I kept saying, I didn’t know how to use the machines or do any landscaping. I didn’t want to get up at the crack of dawn every morning but I really didn’t want to work in that creepy old cemetery by myself every day. He finally talked me into it and soon I was flying around on a riding mower, listening to my Walkman while I cut the grass in the big rear fields, line trimmed around all the trees and stones, pruned bushes, and created flower beds. Pretty soon the cemetery didn’t look old and run down anymore and I found myself hooked on landscaping. I eventually moved back to Northern Illinois as I grew up in Highland Park. I caught on with a small Lake Bluff landscape company and going on 34 years later I haven’t looked back!

I now live in Libertyville with my phenomenal wife Mary, our two grown up boys Brian and Sam, who with his wife Skylar gave us our first grandchild, Peyton the Wonder Boy, three years ago. Peyton keeps us busy but so do the five dogs, fifteen chickens, four birds, and two cats. It is pretty crazy and hectic but we wouldn’t have it any other way.
