Peter Gleick | Co-Founder, Pacific Institute and Author, The Three Ages of Water
Dr. Peter Gleick is a leading scientist, innovator, and communicator on water and climate issues. He co-founded the Pacific Institute in Oakland,California in 1987, one of the most innovative, independent non-governmental research centers, creating and advancing solutions to the world’s most pressing water challenges. He is currently President-emeritus and Senior Fellow at the Institute. Dr. Gleick is a scientist trained at the intersection of hydrology, climatology, and policy. His work has redefined water from the realm of engineers to the world of social justice, sustainability, human rights, and integrated thinking. He developed one of the earliest analyses of the consequences of climate change for water resources, the earliest comprehensive work on water and conflict, and defined basic human needs for water and the human right to water – work that has been used by the United Nations and in human rights court cases. He pioneered the concept of the “soft path for water,” developed the idea of “peak water,” and has written about the history and background of the growing bottled water phenomenon.
Mimi Casteel | Forest Ecologist and Viticulturist at Hope Well Wine
Mimi is the daughter of Ted Casteel and Pat Dudley, co-founders of Bethel Heights Vineyard. Growing up working in the vineyard and winery, Mimi gained such an appreciation for the industry that she promptly left home after high school. Armed with a BA in History and Classics from Tulane University, Mimi spent the next year working in various National Forests across the west. Her adventures fueled her passion for studying botany, forestry, and ecology. Mimi earned her MS from Oregon State University in Forest Science, and spent the next several years working as a botanist and ecologist for the Forest Service, living in the backcountry. She could never get past the longing for the vineyard, and working with the vines. Mimi returned to Bethel Heights in 2005, along with her cousin and childhood best friend Ben to take the helm as second generation winegrowers and owners.

When Ben is not helping Napa’s vineyards adopt 21st century practices, he is spending time with his impressive wife and two wild children in the woods and on the water. Ben currently occupies Nisenan Territory and is a proud alumnus of Sterling College in Northeast Vermont, where he received a BA in Sustainable Agriculture.

Marisa Taylor | Winemaker | Winery & Climate Specialist at Napa Green

During her tenure as winemaker and general manager of Rutherford Hill Winery she supported sustainable farming and green practices from vineyard to cellar and across all winemaking operations. During that time she successfully obtained Napa Green Winery Certification which included the installation and conversion to solar powered energy throughout the facility. She was a featured winemaker in the 6 part PBS series Vintage 2012 and currently serves on the 2nd cohort of the Napa Valley Vintners Leadership Program. With a B.S. in Chemistry and a M.S. in Food Science from the University of California at Davis, she brings both a wealth of knowledge to her work as well as compassion, respect and stewardship for the land.
