About Jeremy Grinwald


Owner / ISA Certified Arborist (RM-2526-A)

I moved to Denver in 1999 after growing up in the woods of Wisconsin. After going to school for a Tool and Die Making and Computer Programming Degree, I realized that I need to work outside. I started my “Green Industry” experience at TruGreen spraying lawns and quickly moved to tree care.

In 2003, I started working for Elk Creek Lawn and Tree Care part-time while I also worked for Highlands Ranch Metro District in their Forestry Department. I had eventually moved to the Natural Resource Departments all while still freelancing for Elk Creek Lawn and Tree Care. In 2010, I started my full-time career with Elk Creek Lawn and Tree Care as Lead Pruner.

As of May 2016, I purchased the Pruning Department from owner Chad Mullins, and have kept the same quality standards that I helped build over the years. Although there was a name change involved with the changing of hands, we still work as one big family.
