It has been seven years since we lost Dr. Alex Shigo. I first had the opportunity to meet him in 1984 when the Colorado Tree Coalition (back then it was the Coilordo Urban Forestry Council) co-sponrored the National Urban Tree Symposium. We began a great friendship, which brought him to Colorado another seven times to share his knowledge with rocky mountain arborists. Going on thirty years, I have witnessed many changes in Arboriculture.
Take a minute or two to think back about how Alex and many of the other great educators helped form your career.
