Board of Directors

Meet our board of directors. These individuals passionately volunteer their time to promote a healthy Lake Wingra through an active watershed community.

FOLW Board of Directors (2022-2023)

Gail Epping Overholt (Co-Chair)

Gail is a senior lecturer at the University of Wisconsin and the Education Coordinator of the UW-Madison Arboretum. She holds a BS in Elementary Science Education (1987) and an MS in Water Resource Management (1993) with an emphasis on wetlands and public education, both degrees from the University of Wisconsin-Madison. Gail has worked in natural resources education for over 25 years, with a good majority of that time focusing on watershed, stormwater and Great Lakes issues. She has held board positions for the Wisconsin Association of Environmental Education, the Wisconsin Wetlands Association, the Friends of Cedarburg Bog, and a short time for Milwaukee Riverkeeper before moving north to the shores of Lake Superior. Her personal goal is to help people of all ages see the “land” as a community of soil, water, and living organisms—not excluding people. Having a special affinity for looking at issues with her eyes on the water, she has enjoyed her time exploring the shores of Lake Wingra and the flora and fauna that call it home.

Tim Kuhman (Vice Chair)

Tim joined the board of directors in 2017.  He is an associate professor of Biological Sciences at Edgewood College.  Tim completed his PhD at the University of Wisconsin-Madison in 2009. His research focused on the role of land-use history in shaping patterns of plant invasion in the southern Appalachains.  Since joining the faculty at Edgewood in 2009, Tim has continued conducting research on invasive plants at the UW Arboretum and around the Madison area.  He has also expanded his research interests to study oak savannah restoration and fire ecology.  Tim teaches a variety of botany and ecology classes, and especially enjoys bringing his students into the field and out on Lake Wingra.  When Tim is not in class or in his office overlooking the lake, he enjoys biking, canoeing, fly fishing, gardening and spending time with his wife and three children.

Sally Lehner (Co-Chair)

Sally joined the Board of Directors in 2021. She grew up in Madison, WI, and has always loved being in and around water. She has fun spending time swimming, canoeing, and paddle boarding in Lake Wingra, and biking, walking, and running around its shore; in wintertime, she likes to cross-country ski on the lake with her husband and ice skate on the lagoon with her family. Sally enjoys volunteering within the community and advocating for urban amenities, like Lake Wingra, for all to enjoy.  She received her BA in International Relations from the University of Southern California in 1999, and her JD from the University of Wisconsin-Madison in 2005, practicing law in Madison until 2011, when she became a stay-at-home mother, now with two boys.

David Thompson

David joined the board in 2010 and was elected Secretary in 2011.  David did his undergraduate work at Stanford University. He majored in Biology and graduated with honors.  Then he obtained his Ph.D. in Zoology in 1974 from the UW-Madison where he specialized in Animal Behavior and Ornithology.  He did his thesis on penguins in the Antarctic.  From 1974-1979, David taught Zoology, Anatomy & Physiology, Ornithology, and Conservation at the UW Center System in Washington County.  During much of this time, he was also a consultant in Wildlife Biology to the U.S. Corps of Engineers.  From 1990-1995, David served as Education Director at the International Crane Foundation in Baraboo, Wisconsin. His interests include gardening with native plants, travel, taking photos that illustrate environmental issues, and serving as a volunteer for a lake similar to Lake Wingra, located in Hawksnest State Park, Massachusetts.

Regan Botsford (Co-Treasurer)

Regan joined the Board of Directors in December 2021. She and her family recently relocated to Madison after spending twenty years in the Bay Area. During her time in California, Regan worked as a development officer for the Sierra Club, UC Berkeley, UCSF and Stanford supporting programs ranging from environmental impact to medicine. Regan enjoys philanthropy and connecting donor intent with purpose, and the relationships created on both sides. Regan and her family can be found around Lake Wingra nearly every day. In the summer, they enjoy swimming, kayaking and exploring around the lake. In the winter, they love to  ice skate on the lagoon. Regan was drawn to the Friends of Lake Wingra to help preserve and protect this beautiful natural resource, and to help advocate for its future.

Katy Bradford (Secretary, Co-Treasurer)

Katy joined the Board of Directors in December 2021. She’s a lifelong resident of the Great Lakes states and first moved to Madison in 2013 for her MS degree in Conservation Biology and Sustainable Development at UW-Madison. She has taken her skills in social science research, evaluation and natural resources outreach to support a variety of grants and programs over the years, and she is currently the program manager for Water Action Volunteers, a UW-Madison Extension and Wisconsin DNR statewide citizen science stream monitoring program. Katy enjoys searching for birds and buzzing pollinators in natural areas around Madison, and strives to plant as many native and, ideally, edible plants as she can in her yard.
