Tim Kenny
Director, Arboretum Education
Statewide Director, Extension Master Gardener Volunteer Program
612-301-3482 • [email protected]
A self-professed plant guy, Tim has woven his passion for plants into his professional life. He has a broad background in the horticulture industry and extensive experience educating learners of all ages in diverse settings: public schools, urban neighborhood gardens, and at the Minnesota Landscape Arboretum since 1993. In his current roles as Director of Arboretum Education and Statewide Director of the Extension Master Gardener Program, Tim leads a creative, dedicated staff of educators who help people of all ages, abilities and circumstances connect with plants through hands-on learning.
Two areas are of special interest to Tim. First, developing and delivering urban, garden-based youth programs that promote science learning, entrepreneurship, leadership development, and contributing to the common good. Second, establishing and sustaining the Arboretum and the Master Gardener Program as trusted sources of research based experiences about issues of our time that relate to gardening and growing plants: clean water, healthy food, urban agriculture, nature-based therapeutics, climate change, pollinators, biodiversity, sustainability, and conservation.
Tim holds three degrees: a Bachelor of Science in Horticulture, a Master of Science in Education, and a Master of Public Affairs. In 2009, he received the University of Minnesota's Distinguished Diversity and Inclusion Staff Award by the University of Minnesota's College of Food, Agricultural, and Natural Resource Sciences for his work. In his free time, he enjoys gardening and photography.

Maria Klein

Maria Klein
Master Gardener Newsletter Editor
[email protected] 952-210-0004
I began my association with the Arboretum as the newsletter editor in 1994, producing the bimonthly membership News, annual reports, promotional and educational fliers, and the like. In 2005, when the new Oswald Visitor Center opened, I helped launch the Reedy Gallery, which I also managed.
In February 2020 (not realizing it was the brink of the pandemic), I rejoined the Education Department as editor of the Master Gardener Volunteer News. This turned out to be a lifesaver on many levels, and I feel so very fortunate to be working again with Arboretum staff and the Master Gardener leadership team.
I have spent my entire communications career in the local nonprofit community, primarily as an editor, educator and advocate. In my spare time I like to garden, read, stitch, travel, ride my new bike in my new neighborhood, and spend time with my utterly remarkable (!) grandchildren.
