Portrait of Beth SummersElizabeth Summers,

Executive Director

Since her childhood in Green Bay, Wisconsin, Beth Summers has held a deep passion for preserving biological diversity. After receiving a B.S. in Wildlife Ecology from the University of Wisconsin, Madison, she worked as an itinerant biologist, following her love of avian ecology to Australia, Nevada, California, Northern Wisconsin, South Carolina, and Florida. She earned an M.S. in Wildlife and Fisheries Science

Appalachia. In 2016, Beth returned to Wisconsin with her family to start a small vegetable business called Birdsong Ridge Farm, where she and her husband have worked to build soil composition and habitat on land previously planted with conventional corn and soybeans. In her spare time, Beth enjoys playing piano and fiddle, gardening, and paddling.


Shelly Gradwell-Brenneman, Programs Administrator 

Raised in a small farming community in central Iowa, Shelly credits her grandparents with inspiring her life’s work in natural resources with their example of conservation leadership in their community. Shelly attended Colorado State University where she earned a B.S. in Environmental Interpretation and completed her internship in Rocky Mountain National Park. After college, she served as a volunteer environmental and ecotourism educator in the rainforests of Costa Rica. She went on to Iowa State University, where she studied sustainable agriculture and earned a M.S. degree in Agronomy and Rural Sociology, while helping launch one of the first community supported agriculture projects in Iowa. She worked with Practical Farmers of Iowa and Iowa State University Extension on several sustainable agriculture and natural resource education projects. The call of wilderness and sustainable fishing brought her to Alaska, where for she worked for the Kenai Watershed Forum and also helped harvest wild salmon at her family fishing camp for many summers.

Dani Heisler winter portraitDani Heisler, Regenerative Agriculture Outreach Specialist

Dani has had a life-long interest in production agriculture and its relationship to the environment. She credits her passion for agricultural diversity to her and her family’s life’s work as farmers and ranchers.

From a young age, Dani had the opportunity to understand and assist in Beef, Dairy, Poultry, Crop, and Vegetable Production, including Peppermint and Spearmint. Dani attended University of Wisconsin River Falls, earning a Bachelor of Science degree focused on Animal Science, Agronomy, and Food Science. While staying rooted in agriculture, Dani has had the opportunity to work across conventional, organic, and large- and small-scale farming operations of all types, with a career
focus on livestock nutrition, ranch management, organic farm transitions, emerging agri-technologies, sales, and marketing. Throughout all her educational and professional agricultural experiences, Dani has consistently valued diversity in farm operations and the robust effect they have on the communities which they support.

In 2014, she and her husband moved to the Viroqua area where they live, farm, and enjoy all the recreational benefits the Tainter Creek Watershed has to offer. Dani is active in the community through board and leadership positions in local organizations, as well as positions representing state-wide efforts.

JoyVietingoffJoy Vietinghoff, Treasurer

Raised on a dairy farm in Northern Illinois, Joy learned all about sustainable farming practices. Her family raised their own livestock and vegetables to feed themselves throughout the year. Growing up on the fam meant hard work, lots of close family time, and never being bored. Respect for the land and water was evident in how they lived each day. After graduating from college with a degree in Accountancy, Joy headed to the big city where she soon realized her heart was still on the farm. She settled for working in a Chicago suburb until she and her husband purchased land near Viroqua where they farmed on weekends until deciding to move here permanently. They put their woodlands in the managed forest program and they worked to prevent creation of a “coal ash dump site” that threatened the area’s water quality. Since moving to Viroqua, Joy has established her own certified public accounting practice. She enjoys working with people to take care of the financial side of conservation. Water quality, sustainable forestry, family farming, and resource conservation are all important to Joy.

Portrait of Winston OstrowWinston Ostrow, Secretary

Winston is a retired lawyer with a lifelong interest in nature and conservation. He became acquainted with our organization while completing the UW Extension’s Master Naturalist course led by Valley Stewardship Network and the Kickapoo Valley Reserve in 2015, and found it to be a good fit for his interests and goals. Winston grew up in California and Ohio. He attended the University of Wisconsin-Madison (BA 1972, JD 1975). He dedicated the majority of his career to work for Godfrey & Kahn, S.C., one of Wisconsin’s largest law firms, where his practice focused on helping individuals and businesses with complex litigation, including environmental and professional liability concerns. In addition to other service and professional recognitions, Winston received awards for pro-bono legal work from The Brown County Izaak Walton League, The Nature Conservancy, and Wisconsin Trout Unlimited. He was legal counsel to Wisconsin Trout Unlimited for many years. Winston and his wife Cheryl moved to Vernon County at the end of 2014. Fly fishing initially attracted them to Southwest Wisconsin, and over the years they came to love the area and its people. Winston’s daughter, Sonja Loomis, is a historian residing in Winston Salem, North Carolina with her husband Greg. Cheryl and Winston spend as much time as possible fishing, hiking, and reading.

Chuck Bolstad portraitChuck Bolstad

Chuck Bolstad considers himself one of the most fortunate people in the world.  He wakes up every morning with his wife of 51 years, Karen, on the same small farm where he grew up and where his grandfather settled in Vernon County over 100 years ago. He recognizes that his grandfather and father engaged in agriculture in ways which are now known to be sound regenerative agriculture practices.  They always maintained and grazed a variety of animals, preserved manure as fertilizer, and valued every inch of soil that barely covered the rocky ridge that is home to the farm. During careers in education and the military, Chuck and Karen needed to move around for job opportunities.  They were able to move back to the Stump Ridge farm permanently in 1993 and return to caring for the land much like Chuck’s father and grandfather by reestablishing low density grazing, installing two erosion control dams, and recently planting several erosion-controlling prairie strips.    Now retired, Chuck spends much of his time volunteering in several local endeavors.    He wholeheartedly supports the mission of Valley Stewardship Network and is pleased to offer his support to their efforts.

Bob Jackson portraitBob Jackson

Bob was born in Chicago and raised in rural Ohio.  He attended college at Miami University, Oxford, Ohio.  He joined the Peace Corps and assisted with water well construction in Niger (Sahel) during the mid-seventies.  He worked as Peace Corps staff in Washington and in multiple countries in Africa (Liberia, Botswana, and Kenya) until 1990.  Bob married Kathleen Sullivan in 1982 (also ex-Peace Corps staff).  They had three sons born while working in Africa.

From 1991-2010 they lived in Minnetonka, Minnesota, where their three sons finished high school and Bob worked as State Director for the federal agency funding AmeriCorps, VISTA, Foster Grandparent, and Senior Companion programs.

Bob and Kathleen moved to the Driftless area in 2010 and now live on small acreage just outside Viroqua.  They enjoy their land and have planted native prairie and a variety of trees, shrubs, fruits, and vegetables there.  Bob has also been a long-time secretary of the local Lions club and supporter/member of numerous  environmental/conservation-oriented organizations.


Jim Munsch portraitJim Munsch, Whole Farm Stewardship Planner

Jim studied Agricultural Engineering at Purdue as background to operating the Indiana farm that had been in the family since after the civil war.   When he was in his junior year, the farm was designated as part of a flood control project and sold to the government.  He stayed on at Purdue and got an MS in Management.  After service as an officer in the US Army in Europe, he took a job in the international department of a manufacturing company in western Wisconsin.  During employment with that company and one in Maryland, the family lived in Japan twice.

Mid-life found him hankering for a return to agriculture, so the family moved to Vernon County to ridge-top farm.  He became a part time beef producer while returning for a decade to a management position in the same company where he had worked previously.  He took early retirement and, while doing management consulting for small companies, direct marketing food producers, grazing farms, and the University of Wisconsin, he continued to raise cattle – currently producing grass-fed beef.

The family lives a mile away from the birthplace of government soil conservation: Coon Valley.  It completes a circle of Jim’s life.  In the 1940-50s, his part of the family in Indiana fully embraced soil conservation.  He was cultivating corn in strips on the contour and maneuvering around terraces before he had a driver’s license.  Saving soil is a North Star for him.
