Wisconsin Chapter Executive Committee Members
Leadership of the WisconsinChapter of the Sierra Club is entrusted to a 15 member volunteer Executive Committee, selected by and representing our membership. Nine Executive Committee members are elected by the Chapter membership at large and serve staggered 3-year terms. Each of our six Local Groups annually appoints a delegate to represent them on the Chapter Executive Committee. Elections are held annually. Details and schedule can be found here.
Gail Syverud, Co-Chair

Don Ferber, Co-Chair
He/Him/His
Four Lakes Group Delegate
d_ferber@sbcglobal.net
Don is an avid outdoors person with an appreciation for nature. As a fan and advocate of Aldo Leopold and his Land Ethic, he believes we need to live in an ethical manner as a member of the land community and in concert with nature and other people. He believes that currently, much of what we are doing is either unwise or unsustainable, it doesn't bring us happiness, and we need to take a different direction. Climate change and energy policy are key areas in determining our future direction and that of the planet. He works actively on climate and energy to set us on a different course. He also enjoys outreach and communications to engage people and educate them about the environment. Since there is no planet B, he figures we have to figure out how to explore, enjoy and protect this one.

Laura studied environmental law at the University of Colorado and passed the Wisconsin Bar in 1999. After her first child was born, she became a full-time Mom and freelance writer. She specializes in writing about science, nature, and social studies and has written three books for children with a fourth coming out this fall.

In this effort, she saw the value of persistent local advocacy and collaboration.
