John Rizza
Colorado State University

After growing up in the northeast and working closely with a logger and arborist, I decided to pursue a career in Natural Resources at Colorado State University where I achieved my B.S. in Natural Resources Management with a minor in Forestry in 2003.  Shortly after graduating college, I earned my ISA Certified Arborist license while working as a Vegetation Manager with a utility company on the West Coast.  I was afforded a unique opportunity to work on a M.S. in Forestry from the University of Tennessee, which I completed in 2007.  After graduating, I spent a few years working in the inland northwest as a consulting forester helping private landowners manage their resources.  Most recently, I was a Forester on the Colorado State Forest where we managed 72,000 acres with a multitude of interests in consideration.  My desire to help private landowners in Colorado to sustainably manage their land has brought me to Colorado State University Extension as the Small Acreage Management Specialist on the west slope.
