Kay Aihla McGrenaghan Cafasso, Instructor
Your Lead Course Instructor is Kay Aihla McGrengahan Cafasso, Permaculture Designer and Director of Sowing Solutions. Kay is a certified permaculture designer practicing the thoughtful design of ecological landscapes. She is also a certified design course instructor who has led over 20 Permaculture Design Certification Courses (PDC’s) to date, and has certified over 500 graduates, while consciously designing and creating supportive learning environments. After documenting ecological design applications in homes and landscapes in arid, temperate and tropical climates worldwide, Kay founded Sowing Solutions Permaculture Design & Education in Western MA, offering ecological garden design and permaculture site planning and consultation services for homeowners and land stewards. She has taught PDC's alongside Geoff Lawton of the Permaculture Research Institute based out of Australia; Kay has taught PDC's in Hawaii with Living Mandala, as well as in the Hudson Valley of New York for the Omega Institute, in the Finger Lakes region of NY for the Finger Lakes Permaculture Institute, and in Massachusetts for Living Routes Study Abroad in EcoVillages. She has inspired the inclusion of permaculture training at educational centers such as Omega Institute and at Greenfield Community College. Kay has worked as teaching staff for Permaculture Teacher Training Courses to guide others in 'Teaching Permaculture Creatively' along with Dave Jacke of Dynamics Ecological Design and Jono Neiger of Regenerative Design Group. Kay has natural building experience, with certificates in Solar Home Design and Natural Building Construction, and has many years of professional experience specializing in earth plasters and natural finishes for straw bale and other natural buildings in the southwestern and northeastern US, as well as in Europe. The educational design approach of this course carries a focus on whole person learning, supportive to all kinds of learners (auditory, visual, kinaesthetic) and weaves in many opportunities for student participation, so that each person can take an active and effective role in their learning. Her teaching style is one that is grounded in the permaculture principles and whole systems thinking. Kay's interests are also in contemplative studies, healing through mindfulness and somatic presence practices, and she is often exploring the bridges between meditation and gardening. She has a passion for creating contemplative and healing outdoor spaces. Kay practices what she teaches: thoughtful and wholistic design of landscapes, agriculture, dwellings, communities, and learning environments.

Her experience is built upon years of living and working on small organic farms, including Hawthorne Valley Farm, where she practiced and taught small-scale vegetable production, as well as at SIrius Community where she is one of the lead growers for the local CSA, and numerous agricultural sites in South America. Increasingly passionate about home-scale food production, Llani studied permaculture and became a certified permaculture teacher in 2010, studying under Dave Jacke of Dynamics Ecological Design. She co-founded a business called Broadfork Permaculture, structured as a cooperative model, that works with clients, installing edible forest gardens and perennial landscapes. Llani has much wisdom to share about life in intentional communities, having spent her childhood years living at a well known ecovillage, as well as much of her adult life coordinating and managing the food systems for residents and neighbors of the community.

Meghan McAuliffe, Affiliated Guest Instructor
During her undergraduate studies in Environmental Sustainability, Meghan focused on food systems and design which led her to completing a permaculture design certification at Sirius EcoVillage, where she now resides. Her connection to yoga grew from her studies in sustainability and permaculture, during which she realized that global problems are just as much cultural as ecological. She received her yoga teacher training certificate from Dhyana Yoga, Philadelphia, and teaches both vinyasa and yin yoga. Through the modalities of permaculture design, herbalism, ayurveda, and yoga she synthesizes principles of ecology with focus on the “inner landscape”, seeing it as a leverage point for not only vibrant health, but outer-system change. Meghan is currently working toward a MA in Contemplative Education from Naropa University, believing that the way we educate about sustainability should reflect the principles of ecology that we teach– in the environment, body, and mind.
