Knoxville native and University of Tennessee graduate, Sam Venable, will emcee the opening Arboriculture Celebration.

David Vandergriff, an extension agent with the University of Tennessee-Tennessee State University Extension Knox County Office and Forestry, Wildlife and Fisheries adjunct assistant professor, is serving as the ISA local host committee conference chair.

“The conference being hosted here is significant in several ways,” he said. “It will bring around 2,000 people from all over the world to Knoxville. Because many of the events are open to the community, a lot of citizens and students will be exposed to different types of arboriculture for the first time.”
