Master Gardener - Statewide Coordinator


The Extension Master Gardener Program started in 1972 in Washington state by Extension Specialist, Dr. David Gibby. Passionate volunteers with a love for gardening were trained to help provide consumer horticulture education to their communities. Since then, the Extension Master Gardener program covers all 50 states and the District of Columbia, has spread internationally covering several provinces of Canada and South Korea.

In 1976 the University of Nevada, Reno Extension Master Gardener program laid down their roots in Northern Nevada. The program grew overtime and eventually sprouted in Southern Nevada in 1993. The UNR Extension Master Gardener program is unique with the variety of gardening zones throughout the state. From the mountains to the deserts, UNR Extension Master Gardeners cover it all.  

Nevada Master Gardeners volunteer over 40,000 hours each year. Nevada Master Gardener volunteers teach classes, offer garden tours, staff information booths at community events, answer questions in-person at Extension offices and through email and telephone, and more!
