Don Ferber, Co-Chair


Four Lakes Group Delegate 

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.

Great Waters Group Delegate 

Linda has a deep concern about climate change and rapid species extinction has prompted her to engage on these issues as a community activist. As a core member of the Milwaukee Equity & Climate Alliance, Linda and her colleagues have successfully advocated for the newly passed resolution committing the city and county to 100% carbon neutrality, along with strong action on racial economic disparity. In this effort, she saw the value of persistent local advocacy and collaboration. In addition to this community work, she serves as president of the Milwaukee Area Land Conservancy, ensuring the preservation and restoration of precious natural landscapes acquired through fee title or conservation easement. She is also a lawyer and member of the American Bar Association. Linda also serves as a member of our Water Team, advocating for stronger factory farm protections.

Tim has been a member for more than twenty-five years and have worked, hiked, and paddled with people who have become friends and with whom they share common values: a fundamental respect for the environment, a desire to preserve native habitats, environmental justice, access to clean water, and the conservation of natural resources. Most of all, he has found a shared sense of respect for the environment in the Sierra activities that he's participated in or led. Tim has practiced law for more than 35 years -- at a large law firm, as a civil rights trial attorney with the US Department of Justice, and as General Counsel at Mitchell Airport where, among other things, he became familiar with and addressed environmental issues.

Coulee Region Group Delegate 

Pat joined the Sierra Club in 1976 because he enjoyed hiking on trails the club had built in the Baraboo Hills. 1980 Coulee Group canoeing outings got him started on paddling.

The world has changed since 1976, and his current efforts include climate, energy, and water quality. Pat is also the board president of Friends of the Blufflands, a group working to protect and preserve bluff prairies and forests in the La Crosse area.
