Larry Justice Extension Master Gardener

"As an Extension Master Gardener volunteer for ten years, I’ve seen the direct benefits from JCEEF.  Foundation grants for hand and power tools and other needed items have made it easier for the volunteers to do their work educating the public and donating services to the county."
