Why We Do What We Do

We want to make a positive difference.  We want to improve the lives of our customers by preserving their beautiful shade trees.  We want to protect and improve the environment.  And we want to give the young people who work for us a livable wage so they can continue their formal education and reach their full potential.

Our History

Our company roots reach back to a three-year long field study begun in 2013.  The purpose of the study was to evaluate methods for controlling the emerald ash borer (EAB).  During the study Tre Wilson, our company founder, saw the devastation from EABs in Michigan, Indiana, Kentucky, and Illinois.  He also gained considerable expertise working with and caring for ash trees.  Tre is a long-time resident of Des Moines and is now directing his life-long passion for nature and preserving native species towards saving our ash trees.

In case you’re interested, some of Tre’s other biological endeavors include recreating prairie habitats, preserving wetlands (Prairie & Wetlands), documenting Iowa’s woodland vegetation, and carrying out field studies to learn more about weeds, bees, fish, birds, wild rats, and other small mammals.  Enjoying nature and improving the environment is what keeps Tre going.

 CFO (Chief Fraxinus Officer)

Sometimes tongue-in-cheek humor needs to be explained.  "Fraxinus" is the genus name for ash trees.  The scientific name for white ash is Fraxinus americana.  For green ash it's Fraxinus pennsylvanica.
