About Good Oak

The Good Oak Team, Summer 2015We took the name “Good Oak” from a chapter in Aldo Leopold's landmark work A Sand County Almanac. In this chapter Leopold narrates the sawing of a dead oak tree for the firewood it will provide to heat his now famous 'shack'. As they saw through each annual growth ring in the massive trunk, he chronicles various historic and conservation events during the year each ring represents.

At Good Oak, our mission is to “To restore ecological health and reestablish native plants to our landscape for the benefit of wildlife and a more sustainable future for humanity.” We have been strongly influenced by Aldo Leopold and his “Land Ethic". So we chose our company name to honor what we feel is the most influential work of conservation literature of the 20th century. We strive to live up to Leopold's ideals and work for positive change.

From that moment on Frank has worked towards the preservation, restoration and re-creation of natural areas. As his knowledge of conservation issues grew, he realized that if we are going to maintain the diversity of our wildlife over time that we are going to have go beyond simply conserving our natural areas and also reintegrate native plants and animals into our human landscapes.

Amy Jo Dusick   Sustainable Landscaping ManagerAmy Jo Dusick at Good Oak headquarters

Amy Jo grew up in the northern coulees of the Driftless Area, within the Lower Chippewa River watershed.

She went on to acquire a Master’s degree in Environment and Resources at the UW-Madison Nelson Institute, looking at the recovery of native soil microbial communities upon the removal of invasive plant populations. Amy Jo also works as a weekend naturalist at the UW-Arboretum and is an ardent advocate for community stewardship and citizen participation as a means to further advance the science of ecology. She currently resides in Madison and can often be seen meandering, seemingly without course, in search of fungi.
