Del Hampton

Del Hampton, treasurer

Born in the St. Paul's Rondo neighborhood, Del is now a longtime resident of Prospect Park. An avid gardener and community organizer, he specializes in setting up and operating community and giving gardens. When he was in third grade, his family moved to a five-acre lot in Woodbury, MN, at a time when it was rural and the first model homes were under construction. After a career in financial services, Del pursued his passion for gardening and became a University of Minnesota Extension Master Gardener in Hennepin County. He served two terms as chair of their Community Programs Committee and developed their Community Garden Support practice. He is currently co-founder and coordinator of the multi-site Prospect Park Community Gardens, and was recently appointed to the State Advisory Board of the University of Minnesota Extension Master Gardeners. He is also a member of the American Dahlia Society.


Renay Leone, secretary

An MSHS member for 20+ years, Renay loves connecting with gardeners. She grew up gardening with her mom and grandma and remembers them taking her swimming in a nearby lake after weeding the vegetable garden on hot summer days. "Not everyone was as fortunate as I was to grow up with an appreciation for and grounding in gardening," Renay says. She believes everyone should have the opportunity to learn about plants and growing. After considering a career as a concert pianist, she chose to go into real estate law, nonprofit work and government land management. When she's not working, Renay enjoys quilting, weeding and walking in nature.

Rhys Williams

As Executive Director of The Good Acre, Rhys develops programs that connect farmers, food makers and communities through good food. He believes the key to strengthening the Twin Cities food system is giving a voice to and creating market opportunities for independent, minority and immigrant farmers. Having worked in nearly every aspect of the food system, he understands what it takes to grow and distribute local food. Growing up in Blind River, Ontario and then the suburbs of Chicago, Rhys earned a degree in Landscape Architecture from Mississippi State University. He served in the Peace Corps in Kenya in the 80’s and relocated to Minnesota in the early 90’s, where he lives with his wife and two daughters.


Debra Kvamme

A fourth-generation farmer, Deb fell in love with plants and soil at a young age. She grew up in a small farming community in northwest Minnesota and learned to garden from her dad and grandparents. After earning an AAS degree in Landscape/Horticulture and a BS in Plant Industry Management from the University of Minnesota in Crookston, she owned a greenhouse and landscaping business and then managed the greenhouse at Rice Creek Gardens. In 2000, she began teaching at Hennepin Technical College, where she currently leads the Horticulture/Greenhouse program. Deb loves teaching the art and science of plant production and has developed curriculum to support growers of all ages and abilities. A hands-on instructor, she believes "people need to get their hands dirty to learn!" Taking her own mantra to heart, she tends a large garden where she can grow what she teaches. 


Judy MacManus

Growing up on a farm in southern Minnesota, Judy experienced the joys of gardening at a young age and grew to understand the importance of stewardship of the land. This background has carried forward in her adult life and is manifested in her love of gardening and concern for the environment. She has been a member of MSHS for almost 25 years and is currently a member of the Garden Club of Ramsey County and also the Saint Paul Garden Club. She earned a degree in art at the College of St. Benedict and pursued a career in advertising, marketing and design. Now retired, she has more time to enjoy her passion for gardening.



Paul Markwardt

An Iowa farm boy turned tax lawyer, Paul learned to garden beside his parents, grandparents, aunts, uncles and other family members. Paul has found that his MSHS membership offers the same type of gardening help—practical instruction, advice and encouragement that make gardening enjoyable. Through his participation on the MSHS board, his goal is to support MSHS in its efforts to continue and to expand these valuable services to the broader community, from lifelong gardeners to people whose interest is newly sparked. Paul's current gardens include perennials, vegetables and a small orchard (which the wildlife, especially pileated woodpeckers and blue jays, may be more successful harvesting). One of his childhood favorites, peonies, continue to enjoy a sweet spot in his gardening heart.
