Wild Rivers Conservancy is pleased to welcome our 2026 slate of new board members. Over the past year, our Board Affairs Committee led a thoughtful and intentional recruitment process to identify leaders who will help advance the Conservancy’s mission and guide our strategic direction into the future.
This year’s recruitment focused on individuals with expertise in water and land conservation and policy, financial development, community engagement, and organizational growth. Together, this incoming class brings a strong mix of professional experience, diverse perspectives, and a shared commitment to protecting the St. Croix and Namekagon Riverway. Just as importantly, they bring energy and enthusiasm that will complement and strengthen our current board.
“We are excited for these new board members to bring their talents and leadership to Wild Rivers Conservancy. They will be a part of implementing our new Strategic Plan as we work to inspire stewardship to forever ensure the rare ecological integrity of the St. Croix and Namekagon Riverway,” said Loralee DiLorenzo, Chair of the Board.
