our staff - greg johnston


Greg began his work in the green industry in the summer of 2006 at his local park district on the Park Maintenance mowing crew. From there he worked with several different landscape companies in Illinois through high school and College at the University of Illinois Urbana-Champaign.  After he graduated in 2010 with a bachelor’s degree in Environmental Science he gained additional experience in both the snow and green industry working with landscape companies in the north east United States and Canada.  Throughout his career he has gained extensive knowledge of landscape plants as well as lawn maintenance.

Greg has served as the purchasing manager at McAdam Landscaping since May of 2016. Through his cultivation of good working relationships with plant and hardscape vendors he is able to gain access to high quality plant and hardscape materials while at the same time keeping prices competitive with the current market.  He also serves on the snow and ice management team in the winter months.

Outside of work Greg enjoys spending time with his wife and children. He is also an avid outdoorsman, spending a lot of his free time hiking, hunting, and fishing.
