Sara Wuerstle

Permaculture Design Course Instructor – Design Mentor

With over two decades of experience working in land stewardship, agriculture and design, Sara has developed a highly integrated understanding of regenerative systems and sustainable development at any scale. More than 50 of her whole system designs have been implemented and continue to be successfully managed. She utilized the whole systems design approach to grow a design and installation business two-fold in less than 5 years in the highly competitive California Bay Area. While there, she was able to not only design but direct the implementation process of the designs to ensure accuracy and effective monitoring for long-term success. Her innovative designs have out performed conventional approaches and act as models for the validity and value of Whole Systems Design by combining Permaculture and Holistic Management. To gain this design acuity, she spent many years studying and working internationally with leading practitioners in the field as well as farmers and growers, while teaching and supporting more than 2 dozen Permaculture Design Certification courses as well as Advanced Permaculture Design Certification courses and related trainings worldwide.

Since then, she has been fully committed to gaining knowledge and experience in permaculture design. She has taken numerous courses with world experts, developed several design projects, organized and facilitated various trainings and events. She also believes permaculture design is the future of landscape architecture and urban planning and has been trying to take these new ideas to her University. In 2015-2016, Eunice embarked on an independent & crowdfunded research around the world to look at mature permaculture projects. She worked and lived with various Permaculture Pioneers, studying in depth their projects and ways of living. For the past years, she has been creating educational materials to share this knowledge with the wider Permaculture community.
